3 and 1/3x + 5.3 = -2. What is x?
Answers
3 1/3x + 5.3 = -2
subtract 5.3 from both sides
3 1/3x = -7.3
write the mixed number as an improper fraction
10/3x = -7.3
rewrite
10x/3 = -7.3
multiply both sides by 3
10x = -21.9
divide both sides by 10
x = -2.19
To check:
3 1/3x + 5.3 = -2
3 1/3(-2.19) + 5.3 =?= -2
-7.3 + 5.3 =?= -2
-2 = -2
This proves that -2.19 is the answer

Julian wants to spend NO MORE than $1,250 on his trip. The airfare is $358. Write & solve an inequality to find the maximum amount he can spend on the rest of his trip.
Answers
X has to be less than or equal to $892 because you have to subtract $358 from the total budget which is $1250
Amount of money Julian can spend on trip= $1250
Amount spent on airfare = $358
Money left for trip = Total money - money spent on airfare= 1250 - 358= $892
So writing an inquality ,
[tex] x\leq 1250-358 [/tex]
where x is amount he can spend on trip.
Solving the inequality,
[tex] x\leq 892 [/tex]
So he can spend less than or equal to $892 on the trip.
Help on 37? Thank you!
Answers
We have to get the denominator of both fractions to be the same so let’s do
3/8 = 18/48
1/6 = 8/48
So if the total is 72 we need to do
18/48 = ?/72
Than cross multiply and let’s change ? into x
48x=1,296
Than divide both sides by 48 to solve for x
x=27
So Paquito scored 27 points
Nows let’s find Jeff’s total points by doing
8/48 = ?/72
Cross multiply once more and change ? To y this time
48y=576
And now divide both sides by 48 to get y
y=12
So Jeff scored 12 points
But that isn’t what the question is asking it’s asking how many did they score together so now all we have to do is
27+12=39
The total amount of points scored by Jeff and Paquito together was 39

Final answer:
To find out how many teams will play in the first round, divide the total number of people by the number of people in each team. In this case, there will be 168 teams playing in the first round.
Explanation:
To find out how many teams will play in the first round, we need to divide the total number of people by the number of people in each team. In this case, we have 1,008 people divided into teams of 6.
To calculate the number of teams, we divide 1,008 by 6: 1,008 ÷ 6 = 168.
Therefore, there will be 168 teams playing in the first round.

In a quadrilateral ABCD, AB ∥ DC and AD ∥ BC . Find the perimeter of ΔCOD if point O is the intersection of the diagonals and AC = 20 in, BD = 20 in, AB = 13 in.
Answers
Answer:
33
Step-by-step explanation:
As the opposite sides of a quadrilateral are parallel and equal in length so
(AB) = (CD) =13
And the diagonals of a quadrilateral bisect each other at their intersection point (O in this case), so length of side OC will be the half of diagonal AC.
(OC) = (AC) /2
(OC)=20/2
(OC) =10
Similarly,
(OD) =10
Now,
Perimeter of Triangle OCD = (OC) + (CD) + (OD)
=10+13+ 10
=33
WXYZ is an isosceles trapezoid with legs WX and YZ and a base XY. If the length of WX is 6x+5, the length of XY is 10x+4 and the length of YZ is 8x-3, find the VALUE OF Y.
Answers
Given is an isosceles trapezoid WXYZ such that WX and YZ are legs of trapezoid with base XY. Also given are the measurements of trapezoid as follows :-
Legs WX = 6x + 5 and YZ = 8x - 3
Base XY = 10x + 4
we know the fact :- "For an isosceles trapezoid, its legs are congruent".
If it is asking for value of the variable 'x', then we can set the expressions of its legs equal and solve for x.
Leg WX = Leg YZ
6x + 5 = 8x - 3
8x - 6x = 5 + 3
2x = 8
x = 4
so, x = 4 would be the answer.
If it is asking for value of base XY, then we could plug the value of x in the expression of XY and compute.
Base XY = 10x + 4
XY = 10(4) + 4
XY = 40 + 4
XY = 44
so, base XY = 44 would be the answer.

A rowing team is practicing on a river. When the boat travels downstream, the current increases the speed of the boat. But when the boat travels upstream, the current decreases the speed of the boat. The team wrote a system letting s represent the speed in calm water and c represent the speed of the current. They found the solution for the system (s, c) to be (14, 6). How fast was the team traveling upstream and downstream?
A. The team traveled at 6 km per hour upstream and 14 km per hour downstream.
B. The team traveled at 14 km per hour upstream and 6 km per hour downstream.
C. The team traveled at 8 km per hour upstream and 20 km per hour downstream.
D. The team traveled at 20 km per hour upstream and 8 km per hour downstream.
Answers
[tex]s=14 \frac{km}{h} [/tex] and [tex]c=6 \frac{km}{h} [/tex]
We also know that when the boat travels downstream, the current increases the speed of the boat; therefore to find the speed of the boat traveling downstream, we just need to add the speed of the boat and the speed of the current:
[tex]Speed_{downstream} =s+c[/tex]
[tex]Speed _{downstream} =14 \frac{km}{h} +6 \frac{km}{h} [/tex]
[tex]Speed_{downstream} =20 \frac{km}{h} [/tex]
Similarly, to find the the speed of the boat traveling upstream, we just need to subtract the speed of the current from the speed of the boat:
[tex]Speed_{upstream} =s-c[/tex]
[tex]Speed_{upstream} =14 \frac{km}{h} -6 \frac{km}{h} [/tex]
[tex]Speed_{upstream} =8 \frac{km}{h} [/tex]
We can conclude that the correct answer is C. The team traveled at 8 km per hour upstream and 20 km per hour downstream.
Final answer:
The team traveled at 8 km per hour upstream and 20 km per hour downstream. Downstream speed is calculated by adding the speed of the boat in calm water to the speed of the current (s + c), and upstream speed by subtracting the current speed from the boat's speed (s - c).
Explanation:
The student is asking about the speeds a rowing team would travel when going upstream and downstream in a river. The system of equations they've solved has given a solution for the speed in calm water, represented by s, and the speed of the current, represented by c, as (14, 6). To find the speed of the team traveling upstream and downstream, we use these values in conjunction with the direction of the current.
When traveling downstream, the current adds to the speed of the boat in calm water, so you would add the speed of the boat and the speed of the current: s + c. This equates to 14 km/h (speed in calm water) + 6 km/h (speed of current) = 20 km/h downstream.
Conversely, when traveling upstream, the current subtracts from the speed of the boat in calm water, so you would subtract the speed of the current from the speed of the boat: s - c. This is 14 km/h (speed in calm water) - 6 km/h (speed of current) = 8 km/h upstream.
Therefore, the correct answer is: C. The team traveled at 8 km per hour upstream and 20 km per hour downstream.

Whatever blocks you have on both sides you can cancel.

The probability that an event will occur is fraction 7 over 8. Which of these best describes the likelihood of the event occurring? Likely Certain Unlikely Impossible
Answers

Hope this helped!
Since 7/8 are quite likely, solution A is the right choice. But it's not certain. It has a 12.5% probability of happening.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, The probability that an event will occur is fraction 7 over 8.
Adjectives include likely and unlikely. When something is likely to occur or is likely to occur, it signifies that it is most likely to occur or that it is anticipated to occur. If something is improbable to occur or unlikely to happen, it suggests that it is most likely not going to.
Likely means there's a big chance that an event will happen. Certain means an event is going to happen, for sure. It will always happen.
In our case,7/8 is very likely. It isn't certain though. There is a 12.5 % chance that it can occur.
therefore, A is the correct answer because 7/8 is very likely. It isn't certain though. There is a 12.5 % chance that it can occur.

Which expression would you use to find the number of outcomes for flipping 4 coins?
Answers
Multiply 2 by 2 by 2 by 2.
Answer:
[tex]2^4[/tex].
Step-by-step explanation:
If we flip a coin then we have two possibilities, i.e., head or tail. So,
Number of outcomes for flipping a coin = 2
If n coins are tossed, then the total number of outcomes is defined by the expression [tex]2^n[/tex].
It is given that the number of coins is 4.
Number of outcomes = [tex]2^4=2\times 2\times 2\times 2=16[/tex]
Hence, he required expression is [tex]2^4[/tex].
A fruit salad consists of blueberries, raspberries, grapes, and cherries. The fruit salad has a total of 280 pieces of fruit. There are twice as many raspberries as blueberries, three times as many grapes as cherries, and four times as many cherries as raspberries. How many cherries are there in the fruit salad?
Answers
2 x bluberries = total raspberries
So raspberries = 2x
Cherries= 4 x raspberries so
Cherries = 8 x
Grapes = 3x cherries so
Grapes = 24x
Total fruit is equal to
X+2x+24x+8x=280
35x=280
Therefore X= 280/35=8
No of cherries in the salad
=8x
=8(8)
=64 cherries in total
Hope this helped and sorry I used shortcuts
Hope u understand
Final answer:
The given ratios indicate there should be 17.5 cherries in the fruit salad, but the number must be a whole number. There appears to be an error in the problem statement, as the conditions cannot be met with the total number of fruits given.
Explanation:
Solving the Fruit Salad Problem
Let's define the number of cherries in the fruit salad as x. According to the problem, there are four times as many cherries as raspberries, so the raspberries would be 4x. Since there are twice as many raspberries as blueberries, the blueberries would be 2(4x) = 8x. Lastly, there are three times as many grapes as cherries, meaning there are 3x grapes. To find out how many cherries are in the fruit salad, we can set up the following equation representing the total pieces of fruit:
x + 4x + 8x + 3x = 280
Adding all terms on the left side of the equation gives:
16x = 280
Dividing both sides by 16 to find the value of x gives:
x = 280 / 16
x = 17.5
Since we cannot have half a cherry in the fruit salad, the correct number of cherries must be a whole number. Therefore, it seems there's a mistake in the original statement regarding the relationship between the number of cherries and other fruits. Without the correct ratios or total pieces of fruit, a precise answer cannot be determined.
