The number of yellow fish at the aquarium is 5 fewer than 3 times the number of blue fish. The table shows how the number of yellow fish, y, depends on the number of blue fish, b. Choose the equation which represents the rule.
Answer:
If you are on USATestPrep (which you most likely are) the correct answer is C.
Step-by-step explanation:
C) y = 3b − 5
It is “5 fewer than 3 times”
Answer:
y = 3b-5
Step-by-step explanation:
The number of yellow fish is 5 fewer than 3 times the number of blue fish. Using b to represent the number of blue fish, 3 times this is 3b; 5 fewer than this is 3b-5. This gives us the equation
y = 3b-5

what is 6 7/8 + 7 5/12
[tex]6 \: \frac{7}{8} \: + 7 \frac{5}{12} [/tex]
Here is your equation:
[tex]6 \frac{7}{8} + 7 \frac{5}{12}[/tex]
As you can see, the denominators, which is the bottom number in the fraction, are different. You need to have the same denominator, so that you can add it. To change the denominators, you need to find the LCM of both denominators, which is 8 and 12. To find the LCM, first list the multiples of both numbers and see what is common.
[tex]8 - 8, 16, 24, 32, 40, 48, 56 \\12-12, 24, 36, 48[/tex]
The only common number is 48. That means you need to change both fractions so that they have a denominator of 48.
[tex]6 \frac{7 \times 6}{8 \times 6} \rightarrow 6 \frac{49}{48}[/tex]
[tex]7 \frac{5 \times 4}{12 \times 4} \rightarrow 7 \frac{20}{48}[/tex]
Here is your new equation:
[tex]6 \frac{49}{56} + 7 \frac{20}{48}[/tex]
Add:
[tex]6 \frac{49}{48} + 7 \frac{20}{48} = 13 \frac{69}{48}[/tex]
Simplify:
[tex]13 \frac{69}{48} \rightarrow 14 \frac{21}{48} \rightarrow 14 \frac{7}{16}[/tex]
Your answer is 14 [tex]\frac{7}{16}[/tex]

Tickets to a concert cost $2 for children, $3 for teenagers and $5 for adults. When 570 people attended the concert, the total ticket receipts were $1950. Three-fourths as many teenagers as children attended. How many adults attended?
Answer: 220
Step-by-step explanation:
Children (x): $2
Teens (y): $3, [tex]\frac{3}{4}x[/tex]
Adults: (z): $5
Quantity: x + y + z = 570 ⇒ x + [tex]\frac{3}{4}x[/tex] + z = 570 ⇒ 1.75x + z = 570
Cost: 2x + 3y + 5z = 1950 ⇒ 2x + 3[tex](\frac{3}{4}x)[/tex] + 5z = 1950 ⇒ 2x + 2.25x + 5z = 1950 ⇒ 4.25x + 5z = 1950
Qty: 1.75x + z = 570 → 5(1.75x + z = 570) → 8.75x + 5z = 2850
Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → -4.25x - 5z = -1950
4.50x = 900
x = 200
Teens (y): [tex]\frac{3}{4}x[/tex]
y = [tex]\frac{3}{4}(200)[/tex]
= [tex]\frac{600}{4}[/tex]
= 150
Quantity: x + y + z = 570
200 + 150 + z = 570
350 + z = 570
z = 220
a line contain the points (82,-96) and (87,-86) . what is the slope of the line in simplification form ?
y=2x−26 because the form for standard slope is: y=mx+b
you have to find the slope by doing y-y/x-x and then you plug the slope you get into m and then you pick a point; either (82,-96) or (87,-86) and you plug it in for the x and y in y=mx+b and you work out the equation from there.

Which of the following is a true statement describing the pattern 20, 25, 30, 35,…? The pattern contains only even numbers. The pattern contains only odd numbers. The pattern is decreasing. The pattern contains only factors of 5.
In this pattern all are divisible by 5
20[tex] =4×5[/tex] i.e. divisible by 5
25[tex] = 5×5 [/tex] is divisible by 5
30[tex] =2×3×5[/tex] is divisible by 5
35[tex] =7×5 [/tex] is divisible by 5
Hence the pattern contain factor 5
The statement that correctly describes the pattern 20, 25, 30, 35, ... is that it contains only factors of 5.
The given sequence of numbers is 20, 25, 30, 35,... and the correct statement describing this pattern is that it contains only factors of 5. This is because each number in the sequence is a multiple of 5 and can be divided by 5 without leaving a remainder. The sequence is not exclusively even or odd numbers, as it contains both (20 and 30 are even, while 25 and 35 are odd). Also, the pattern is not decreasing; it is instead increasing by increments of 5.

if tickets for a amusement park cost $10 for adults and $6 for children.What is the total cost for 2 adults ad 3 children
(10)2 x (6)3 = 38
It will cost $38 for 2 adult's and 3 children's tickets.
Suppose f(x)=2x−5. Find the value of f(3)
can someone please help me with this?
f(3) = 1
substitute x = 3 into f(x)
f(3) = (2 × 3) - 5 = 6 - 5 = 1
To find the value of f(3) for the function f(x) = 2x - 5, substitute x = 3 into the function. The value of f(3) is 1.
Explanation:To find the value of f(3) for the function f(x) = 2x - 5, we substitute x = 3 into the function.
So, f(3) = 2(3) - 5.
Simplifying further, we get f(3) = 6 - 5 = 1.

35 rounded to the nearest hundred
Answer and Explanation: 35 rounded to the nearest 100 is 0. To round to the nearest hundred, you need to first identify the hundreds that are closest to the number you are rounding. For 35, the closest hundred that is lower than 35 is 0, and the closest 100 that is higher than 35 is 100.
The rounding of 35 to the nearest hundred gives us 0.
To round 35 to the nearest hundred, we need to determine which hundred it's closest to. In this case, we can see that 35 is near to 0 than to 100.
When rounding to the nearest hundred, we look at the number in the knock outs place.
However, we round up, and if it's lower than 5, If it's 5 or lesser.
In the number 35, the knockouts number is 3.
Since 3 is lower than 5, we round down.
When we round down, we keep the hundreds number as is and replace all the integers to the right with bottoms.
Thus, rounding 35 to the nearest hundred gives us 0.

Given: ABC is similar to XYC. If BY = 4, YC = 7, XC = 10. Which of the following proportions could be used to solve for AC? 4/7 = 10/AC 7/4 = 10/AC 4/11 = 10/AC 7/11 = 10/AC
Answer: The correct option is 4th, i.e., [tex]\frac{7}{11}= \frac{10}{AC}[/tex].
Explanation:
It is given that ABC is similar to XYC. If BY = 4, YC = 7, XC = 10.
Draw a diagram by using the given information.
From the figure,
[tex]BC=BY+YC[/tex]
[tex]BC=4+7[/tex]
[tex]BC=11[/tex]
If the two triangles are similar then their corresponding sides are is in proportion and the corresponding angle are same.
[tex]\frac{YC}{BC}=\frac{XC}{AC}[/tex]
[tex]\frac{7}{11}=\frac{10}{AC}[/tex]
Therefore, the correct option is 4th.
