Answer: the top box can be the linear equation y=40x+15 and the bottom box is 40
Step-by-step explanation:
If you swim 15 more minutes than your friend and your swam 55 minutes, that means your friend only swam 40 minutes. The set amount of time that your friend swims for x is 40 minutes. So the additional time you swim is b, 15 minutes.

The vertices of trapezoid ABCD are A(3,-2), B(7,-2), C(8,- 7), and D(1, - 7). Graph ABCD and
A'B'C'D', its image after a reflection across the x-axis.
Answers
Answer:
B
Step-by-step explanation:
When reflecting a figure over the x-axis, flip the sign of the y-coordinates for the vertices.
For this figure, trapezoid ABCD, the vertices are:
A (3, -2)
B (7, -2)
C (8, -7)
D (1, -7)
Flipping the signs of the y-coordinates gives us:
A (3, 2)
B (7, 2)
C (8, 7)
D (1, 7)
The only graph that has trapezoid A'B'C'D' with vertices matching these four values is the graph for B, so the answer is B.

7. A scatter plot was created to show the relationship
between the number of staff members and students
at various schools. The scatter plot's trend line has an
equation of y = 0.1x + 18, where y is the total number
of staff members and x is the total number of
students.
Use the equation to predict the number of students in
a school with 120 staff members.
A. 1,038 students
B. 30 students
C. 890 students
D. 1,020 students
Answers
Answer:
1020 students
Step-by-step explanation:
Given the trend line equation :
y = 0.1x + 18,
where y is the total number of staff members and x is the total number of students.
Using the equation, the predicted number of students in a school with 120 staffs ;
y = 120
y = 0.1x + 18
120 = 0.1x + 18
120 - 18 = 0.1x
102 = 0.1x
x = 102 / 0.1
= 1020 students
Find the solution to the following system using substitution or elimination:
Answers
Answer:
D. (-2, 1).
Step-by-step explanation:
y = 3x + 7
y = -2x - 3
AS the expressions on the right are both equal to y:
3x + 7 = -2x - 3
3x + 2x = -3 - 7
5x = -10
x = -2
Plug this into the first equation:
y = 3(-2) + 7
y = 1.

Step-by-step explanation:
Angle 1 is inside a triangle. Angles in a triangle add up to 180.
Angle 1 = 180 - 90 - 40 = 50.
Angle 2 is on a straight line (180 degrees), shared with angle 1. Therefore, angle 2 is 180 - Angle 1 = 130. Angle 3 and 4 can be calculated the same way Angle 2 was calculated (1=3, 2=4).
Angle 5 is 180 - 90 - Angle 3 which is 180-90-50 which is 40.
Angle 6 is 180 - Angle 5 = 180 - 40 = 140.
Angle 8 is the same as Angle 6
Finally, Angle 7 is 180-90 = 90.
Hope that helped!

Evaluate the algebraic expression 4v-3 if v= -5.explain
Answers
Answer:
-23
Step-by-step explanation:
Given 4v-3
evaluate when v = -5
So basically we want to find the value of the expression when the variable (v) equals -5
so
* plug in -5 for v*
4(-5)-3
4*-5=-20
-20-3=-23
So we can conclude that when v = -5 the value of the expression is -23
Answer:
4v-3 = -23Explanation:
given the expression: 4v-3
if v = -5
4v-3 (let's subsitute v)
4v-3 = 4×(-5)-3
4v-3 = -20 - 3
4v-3 = -23

Step-by-step explanation:
The given recipe makes 8 bags.
To make 16 bags, Lily needs twice as many ingredients because 8 + 8 = 16.
Since 1 cup of raisins makes 8 bags, 2 cups of raisins will make 16 bags.
To show the mathematical way:
Variable w = number of cups of raisins
1/8 = w/16
Cross multiply
1 × 16 = 8 × w
16 = 8w
2 = w
2 cups of pretzels makes 8 bags so 6 cups of preztels will make how many bags?
Set up an equation:
Variable x = number of bags
2/8 = 6/x
Cross multiply
2 × x = 8 × 6
2x = 48
x = 24
6 cups of pretzels will make 24 bags.
If 0.5 cup of pecans = 2.5 cups of crackers, then 1 cup of pecans = y cups of crackers?
Variable y = number of cups of crackers
Set up equation:
0.5/2.5 = 1/y
Cross multiply
0.5 × y = 2.5 × 1
0.5y = 2.5
y = 5
1 cup of pecans will need 5 cups of crackers
2 cups of pretzels = 8 bags, so 1 cup of preztels = z bags?
Variable z = number of bags
Set up equation:
2/8 = 1/z
Cross multiply
2 × z = 8 × 1
2z = 8
z = 4
10^8/10^4 Simplify the expression. Write your answer as a power.
Answers
This is an exponential expression with 10 as the base and 4 as the exponent.
=============================================
Explanation:
We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.
The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.
Side note: 10^4 = 10,000 = ten thousand

Answers
Answer: she can get 50 adult t-shirts
Step-by-step explanation:
55 x 3.25 = 178.75
625-178.75 = 446.25
446.25 - 5.75 = 440.5
440.5-5.75 = 434.75
434.75-5.75 = 429
429-5.75 = 423.25
423.25-5.75 = 417.5
417.5-5.75 = 411.75
411.75-5.75 = 406
406-5.75 = 400.25
400.25-5.75 = 394.5
394.5-5.75 = 388.75
388.75-5.75 = 383
383-5.75 = 377.25
377.25-5.75 = 371.5
371.5-5.75 = 365.75
365.75-5.75 = 360
360-5.75 =354.25
354.25-5.75 = 348.5
348.5-5.75 = 342.75
342.75-5.75 = 337
337-5.75 = 331.25
331.25-5.75 = 325.5
325.5-5.75 = 319.75
319.75-5.75 = 314
314-5.75 = 308.25
308.25-5.75 = 302.5
302.5-5.75 = 296.75
296.75-5.75 = 291
291-5.75 = 285.25
285.25-5.75 = 279.5
279.5-5.75 = 273.75
273.75-5.75 = 268
268-5.75 = 262.25
262.25-11.5 = 250.75
250.75-11.5 = 239.25
239.25-11.5 = 227.75
227.75-11.5 = 216.25
216.25-11.5 = 204.75
204.75-11.5 = 193.25
193.25-11.5 = 181.75
181.75-11.5 = 170.25
170.25-11.5 = 158.75
158.75-11.5 = 147.25
147.25-11.5 = 135.75
135.75-11.5 = 124.25
124.25-11.5 = 112.75
112.75-11.5 = 101.25
101.25-11.5 = 89.75
89.75-11.5 = 78.25
78.25-11.5 =66.75
66.75-11.5 = 55.25
55.25-11.5 = 43.75
43.75-11.5 = 32.25
32.25-11.5 = 20.75
20.75-11.5 = 9.25
