A doll and a toy t-rex cost $33 together. If the t-rex toy costs $9.50 more than the doll, how much did the doll cost?
Answer:
The cost of the doll is $11.75
Step-by-step explanation:
Let
x ----> the cost of the doll
y ----> the cost of the toy t-rex
we know that
[tex]x+y=33[/tex] -----> equation A
[tex]y=x+9.50[/tex] ----> equation B
substitute equation B in equation A and solve for x
[tex]x+(x+9.50)=33\\2x+9.50=33\\2x=33-9.50\\2x=23.50\\x=\$11.75[/tex]
therefore
The cost of the doll is $11.75
Answer:
Doll cost = $11.75.
Step-by-step explanation:
Given :A doll and a toy t-rex cost $33 together. If the t-rex toy costs $9.50 more than the doll.
To find : how much did the doll cost.
Solution : We have given
A doll and a toy t-rex cost $33 together.
Let the Doll cost = x .
According to question .
t-rex toy costs $9.50 more than the doll.
T-rex cost = $9.50+ x .
Then, A doll and a toy t-rex cost $33 together.
Doll cost + T oy t-rex cost = $33
Plugging the values
x + $9.50+ x =$33 .
2x + $9.50 =$33 .
On subtracting both sides by $9.50
2x =33 - 9.50
2x = 23.5.
On dividing both sides b y 2
x = $11.75
Doll cost =$11.75
Toy Cost = 9.50 +11.75.
Toy Cost = $21.25
Therefore, Doll cost = $11.75.

Find the two square roots of 4
Whenever you take the square root of a number you get a negative and a positive result: √ 4 = ± 2 or { − 2 , 2 } − 2 ⋅ − 2 = 4 and 2 × 2 = 4
The two square roots of 4 are 2 and -2.
What is square root?The factor of a number that, when multiplied by itself, yields the original number is known as the square root of the number. Special exponents include squares and square roots. Think about the number 9. When the number 3 is multiplied by itself, the result is 9. This can be expressed as either 3² or 3 × 3.
Given:
The number is 4,
Factorize the number as shown below,
4 = 2 × 2
Calculate the value of the square root of 4 as shown below,
√4 = √(2 × 2)
√4 = ±2
√4 = 2 or -2
Check as:
-2 × -2 = 4
2 × 2 = 4

a vendor sold 228 sodas & hotdogs. the number of sodas sold was 3 times the number of hot dogs sold. Find the number of sodas and hotdogs sold
Final answer:
To solve the system of equations, we determined the number of hotdogs sold as 'h' and found out that the vendor sold 57 hotdogs and 171 sodas.
Explanation:
The problem given is a system of equations question where we need to find the number of sodas and hotdogs sold by a vendor when given the total sales and the ratio of sodas to hotdogs. To solve this, we'll denote the number of hot dogs sold as 'h' and the number of sodas sold as 's'. According to the problem, the total number of items sold is 228, which gives us the equation:
s + h = 228.
It's also given that the number of sodas sold is three times the number of hot dogs sold. This is our second equation:
s = 3h.
Now we can substitute the second equation into the first, yielding:
3h + h = 228,
which simplifies to:
4h = 228.
Dividing both sides by 4 gives:
h = 57.
With the knowledge that h = 57, we use s = 3h to find that:
s = 3 × 57,
s = 171.
Therefore, the vendor sold 57 hotdogs and 171 sodas.

Which of the following would be the most logical first step to solving this
quadratic equation?
x2 -5x + 6 = 0
Answer:
Step-by-step explanation:
There are many ways to solve this:
- factorising
- formula
- perfect squaring
FACTORISING:
The first step would be to multiple the coefficient of x^2 and 6.
Then find which of the factors of 6 sum up to 5. (In this case it is 2 and 3.)
So you would rewrite the equation like this:
x2 -3x -2x + 6 = 0
Then factorise
x(x-3) - 2(x-3) = 0
Then factorise again
(x-2)(x-3) = 0
So if we were to divide each side by (x-2)
(x-3) =0
so x = 3
OR
if we were to divide each side by (x-3)
(x-2) = 0
x = 2
FORMULA:
The formula is
-b±[tex]{\sqrt{b^2 -4ac}[/tex] / 2a
where
ax^2 + bx + c = 0
The first step would be to substitute.
PERFECT SQUARING:
The first step would be to half the second term.
[tex](x - \frac{5}{2})^{2} - \frac{25}{4} - 6 = 0[/tex]
Then solve for x.

Answer:
$173.90
Step-by-step explanation:
The most obvious way to answer this question is to multiply $9.40 by 18.5
This would result in 173.90.
But I realize nobody like to deal with decimals in a multiplication problem, so here's the way I would do it (especially if you don't have a calculator!)
The strategy is to break it down!
Multiply $9.40 x 18 hours to start, since this is easier.
[tex]9.4 x 18 = 169.2[/tex]
So, that's $169.20 for 18 hours of work.
We aren't finished, because Abdel worked for 18.5 hours.
So, what half of $9.40?
[tex]9.4 / 2[/tex]
= 4.7
-or-
$4.70
So, knowing that Abdel makes $4.70 in half an hour, lets just add that onto the $169.20 we got earlier.
169.2 + 4.7 = 173.9
-or-
$173.90 for 18.5 hours of work!

If DM=25 what is the value of r?
Answer:
r=12.5 units
Step-by-step explanation:
Well assuming that DM means diameter of a circle, then r should be the radius of the circle.
Diameter of a circle is twice the radius of the circle, hence with the value of Diameter, you should half it to get the value of radius.
Given diameter =25
Radius will be= 25/2 = 12.5 units
The value of r is 12.
This is because the line segment DM is made up of two segments, DG and GM.
We are given that the length of DM is 25, and the lengths of DG and GM are r+2 and 2r-13, respectively.
Therefore, we can set up the following equation:
r+2 + 2r-13 = 25
Combining like terms, we get:
3r - 11 = 25
Adding 11 to both sides, we get:
3r = 36
Dividing both sides by 3, we get:
r = 12
Therefore, the value of r is 12.

Answer:
The slope of the line is 7/2.
Step-by-step explanation:
If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the slope of the line is

Using the above formula, the slope of the line is
[tex]m=\frac{14-0}{4-0}[/tex]
[tex]m=\frac{14}{4}[/tex]

What is mt?
A. 28º
B. 62º
C. 90º
D. 152º
Answer:
B. 62°
Step-by-step explanation:
According to the Supplementary Angles Theorem, in this case, ∠s and 152° form a straight angle, so you use the Supplementary Angles Theorem:
-152° + 180 = 28°; 28° = m∠s
Then, use the Triangular Interior Angles Theorem to find the m∠t:
28° + 90° = 118°
↑
∠s
-118° + 180° = 62°; 62° = m∠t

Answer: Option 'b' is correct.
Step-by-step explanation:
Since we have given that
Measure of exterior angle = 152°
and measure of one opposite interior angle = 90°
Measure of another opposite interior angle be 't'.
As we know that
Sum of interior angle is equal to exterior angle.
[tex]90^\circ+t=152^\circ\\\\t=152^\circ-90^\circ\\\\t=62^\circ[/tex]
Hence, the measure of t is 62°.
Therefore, Option 'b' is correct.
