Answer:

B 60

Step-by-step explanation:

Do not let all the extra triangles on the outside trip you out. The shape is a trapezoid which total should equal 360. Add all the angles up and subtract from 360 to get 60

$\huge \bf༆ Answer ༄$

The equivalent expressions are ~

<h3>Question : 1 </h3>

$\sf \: - 3(7 + 5g)$

$\sf - 21 - 15g$

$\sf- 15g - 21$

<h3>Question : 2</h3>

$\sf \:( x + 7) + 3y$

$\sf \: x + 7 + 3y$

$\sf \: x + 3y + 7$

<h3>Question : 3 </h3>

Find the equation of a line perpendicular to 4x+2y=3 that contains the point (1,5)

grin007 [14]

Answer:

x -2y = -9

Step-by-step explanation:

We can start by swapping the coefficients of x and y, then negating one of them. We can finish by evaluating the expression at the given point to find the constant.

2x -4y = constant

2(1) -4(5) = -18 = constant

So, an equation could be ...

2x -4y = -18

We notice that all of the coefficients of this equation are divisible by 2, so we can remove a factor of 2 from the equation:

x -2y = -9

a student earns a 90 on a test for missing one question incorrectly and earns a 70 for answering three incorrectly.What is the s

Rufina [12.5K]

I got -10

1. create two ordered pairs based on the data so (1, 90) and (3, 70)

2. plug into the slope formula so (70 - 90)/(3 - 1)

then it's -20/2, which is -10
