7 - 2x if x = -4 And show your work

Mathematics
1 answer:
uysha [10]3 years ago
8 0

Answer: 15

Step-by-step explanation: To evaluate an expression, we plug the value of the variable into the expression and simplify.

Since we have 7 - 2x and x is -4, we have 7 - 2(-4).

Simplifying from here, 2(-4) is -8 so we have 7 - (-8).

Now, remember that a a minus sign followed by a

negative sign turns the two signs into a plus sign.

So 7 - (-8) can be thought of as 7 + (+8) which is 15.

How would I solve for x?​
vaieri [72.5K]

Answer:

x = 65

Step-by-step explanation:

First, we calculate the unknown angle of the left triangle and right triangle:180 - 62 - 50 = 68

Unknown angle for left triangle⬆️

180 - 80 - 53 = 47

Unknown angle for right triangle⬆️

Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

180 - 68 - 47 = 65

The angle 65° and angle of x are vertical angle.(both are equal)

So... <u>x= 65°</u>

madam [21]
You're really just finding the volume of the cargo-carry part.

V= L x W x H

V= 8.3m x 3m x 4.2m

V= 104.58 m3 or 105 m3 (rounded)

ANSWER: The maximum volume of sand Billy's truck can carry is about 105 m3.
