Answer: 22
Step-by-step explanation:
(7x+5) + (3x-5) + 90 = 180
10x + 90 =180
-90 -90
10x =90

To find the missing angles of the triangle we must first make an equation using what we know. A triangles sum is equal to 180 degrees, and a box indicator represents a 90 degree angle. With that we do this,
(7x+5)+(3x-5)+90=180
7x+5+3x-5+90=180
7x+3x+90=180
10x+90=180
10x=180-90
10x=90
10x/10=90/10
x=9
Now we find each individual missing angle,
(3x-5)
3(9)-5
27-5
22 degrees
(7x+5)
7(9)+5
63+5
68 degrees
Check to make sure it equals 180 degrees
22+68+90=180

Answer:
Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.
Step-by-step explanation:
Given
Minutes: 10 || 16 || ? || 48
-----Miles: 2.5 || 4 || 7.5 || 12
Required
Which statements solve for the missing value?
First, we need to calculate the ratio of minutes to mile
[tex]Ratio = \frac{Minutes}{Mile}[/tex]
When minutes = 16; mile = 4
So, we have:
[tex]Ratio = \frac{16}{4}[/tex]
[tex]Ratio = 4[/tex]
Next, we multiply the ratio by 7.5
[tex]Minutes = Ratio * 7.5[/tex]
[tex]Minutes =4 * 7.5[/tex]
[tex]Minutes = 30[/tex]
Hence, option B answers the question.

Which streets are parallel? Check all that apply. c || d c || e c || f d || e d || f e || f
Answers
Answer:
The answer is "c || f and d || e".
Step-by-step explanation:
Its acute collision angle between e and t is:
[tex]\to 180^{\circ}- 112^{\circ} = 68^{\circ}[/tex]
Its angle refers to the acute corner of d, so d and e are parallel to its extreme angle of crossroads between c and t is:
[tex]\to 180^{\circ} -114^{\circ} = 66^{\circ}[/tex]
Its angle is identical to the acute angle of, f so, that c and f are parallel. [tex]d | |e, c || f[/tex]
All "corresponding" to extreme angles at crossings of t. Thus the associated points are connected to their congruence.

As per transformation of graph, h(x) = ([tex]\frac{1}{5}[/tex])x² + 12 represents that the graph of f(x) is horizontally compressed by a factor of 5 and shifted up 12 units.
What is the transformation of a graph?"Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph. It's a common type of problem in algebra, specifically the modification of algebraic equations.
Given, the graph is f(x) = x².
We know that, at the time of horizontally compressing a graph we need to multiply it by a factor of ([tex]\frac{1}{a}[/tex]).
Again, at the time of shifting a graph up we need to add a positive number of (b).
Therefore, a = 5 and b = 12.
Now, if we horizontally compress f(x) it by a factor of ([tex]\frac{1}{5}[/tex]) then it be ([tex]\frac{1}{5}[/tex])x².
Again, if we shifted up f(x) by 12 units, then it be ([tex]\frac{1}{5}[/tex])x² + 12.
Therefore, h(x) = ([tex]\frac{1}{5}[/tex])x² + 12 represents that the graph of f(x) is horizontally compressed by a factor of 5 and shifted 12 units up.

Write an
equation for the linear function f satisfying the given conditions.
1) f(-1) = -5 and f(5) = 7
Answers
Answer: f(x) = 2x - 3
===================================================
We're given f(-1) = -5 and f(5) = 7
This means we know the two points (-1,-5) and (5,7) are on the line.
Find the slope
m = (y2-y1)/(x2-x1)
m = (7-(-5))/(5-(-1))
m = (7+5)/(5+1)
m = 12/6
m = 2
The slope is 2.
Use this along with (x1,y1) to find the equation. We'll use point slope form
y - y1 = m(x - x1)
y - (-5) = 2(x - (-1))
y + 5 = 2(x + 1)
y = 2x + 2 - 5
y = 2x - 3
f(x) = 2x - 3

Triangle BAK has side lengths: BA=60, AK=38, and KB=36
Triangle JOL has side lengths: JO=50, OL=28, and LJ=26.
Calculating the ratios of the corresponding side lengths:
BA/JO=60/50=1.2

Step-by-step explanation:
Let the Andrew's number is x
Tamar tells Andrew to think of a number, multiply it by five andsubtract three from the result
5x - 3
Manoj tells Andrew to think of a number, add five and multiply the result by three.(x +5)*3
as he was getting the same answer so both the numbers will be equal
5x -3 = (x+5)*3
5x - 3 = 3x + 15
2x = 18
x = 9
a. Andrew's started with number 9
b. (1) 5x- 3 = 5*9 - 3

(2) (x + 5)*3
= 14*3 = 42
c. Think of a number, then multiply it with 4 then add 6 in it
Think of a number add 12 in it then then double it.

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
We need to find the coordinates of P which is equidistant from the endpoints A=(-2,1) and B=(4,-1).
Calculate the midpoint:

How much does a hat cost?
Answers
Answer:
A t-shirt costs 10.00 pounds and a hat costs 3.00 pounds.
Step-by-step explanation:
x is a t-shirt
y is a hat
9x + y = 93.00
4x + y = 43.00
(9x + y) - (4x + y) = 93.00 - 43.00
9x + y - 4x - y = 50.00
5x = 50.00
x = 50.00/5
x = 10.00 [a t-shirt costs 10.00]
4x + y = 43.00
4×10.00 + y = 43.00
40.00 + y = 43.00
y = 43.00 - 40.00
y = 3.00 [a hat costs 3.00]

Answer:
Laura will have exactly $72.00 after purchasing the bicycle.
Step-by-step explanation:
We are given that Laura ends $115 per month of babysitting.
We also learn that she wants to save her money from June and July, which means she wants to save her money over a period of two months.
Therefore, she will earn $115 twice.
[tex]\displaystyle{\$115 \times 2 = \$230}[/tex]
Then, she wants to purchase a bicycle that costs $158, so we need to subtract the cost of the bicycle from her total earnings.
[tex]\$230 - \$158 = \$72[/tex]
Therefore, Laura will have exactly $72.00 remaining after her purchase.
