Answer:

-56

Step-by-step explanation:

First, let's solve for x in 5x = -35.

Step 1: Divide both sides by 5.

  • \frac{5x}{5} = \frac{-35}{5}
  • x = -7

Now, that we know the value of x is equal to -7, let's simplify the expression -28 + 4x:

  • -28 + 4(-7)
  • -28 - 28
  • -56

Therefore, the value of -28 + 4x is equal to -56 when x is equal to -7.

Answer: -56

Step-by-step explanation: if u take -35/5 u get -7 so x=-7 so then u get -28+4(-7) so 4 times -7 equals -28 so -28 + -28= -56

This one is a tough one. If you can explain it to me that’ll me great.
Crazy boy [7]

Answer:

C. 73 if I have read the given angle measurements correctly.

The angle measurements I see are:

219^\circ

(x-50)^\circ

(x+45)^\circ.

Step-by-step explanation:

Those angles together form a full rotation. A full rotation is equal to 360 degrees.

So we have the following equation to solve:

219+(x-50)+(x+45)=360

Combine like terms:

(x+x)+(219-50+45)=360

Simplify:

2x+(219-5)=360

2x+214=360

Divide both sides be 2:

x+107=180

Subtract 107 on both sides:

x=180-107

x=73

If g(x) = 4 square root of x then g(45) is
AlladinOne [14]
Hi,

So we have g(x) = 4√(x).  We're looking for g(45).  Think of it like this: whatever number is in the place of x in g(x), just place that number AS x.

Therefore, we have :
g(45) = 4√(45) ⇒ (4) × (√(45)) ⇒ (4)(3√(5)) = 12√(5).

-Hope this helps!

A sports ball has a diameter of 27 cm. Find the volume of the ball. cm.) Round your answer to the nearest tenth if necessary.​
Anestetic [448]
To calculate the volume of a sphere you must use the formula
v=4/3pir^3

The radius (r) is half of the diameter
r=13.5

v=4/3pi13.5^3
v=10305.99

Therefore the volume of the sports ball is 10306cm^3 (to the nearest tenth)
