Answer:

1. B) x = 12

2.C)  -5

3. A) 4

7. C) -4

8. A) -4x -6 = 16x

9. B) 29x = 0

Step-by-step explanation:

okay, number 7 you have to distribute -3 to 6 to get -18. So you get 4 -(3*2y) - 18 = 10. add 18 to both sides to get 4 -(3*2y) = 28. subtract the 4. -(3*2y) = 24. Rever the negative. (3*2y) = -24. Divid by 3; 2y = -8. And divide by 2; y = -4.

Same with number 8 but keeping the 16x.

4x - 2 (4x + 3) = 16x

4x - 8x + - 6 = 16x

-4x + -6 = 16x

9.

4(3 - 4x) = 12

3 - 4x = 3

-4x = 0

x = 0

Now you know x = 0 so anything multipied

with the x is 0. The answer is B.

I hope this helped :)

Show how to solve the problem 378×6 using place value with regrouping. Explain how you knew when to regroup
nekit [7.7K]
<span>1. 6 (378) = 2268 = (189 + 189)6


Properties are:
Addition, you can have 6 + 107 = 113 </span>
<span>Commutative Property by moving: 107 + 6 = 113 </span>
<span>Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 </span>
<span>Distributive Property by allotting: 2 (3) + 107 = 113   </span>

<span>Multiplication, you can have 6 x 107 = 642 </span>
<span>Commutative Property by moving: 107 x 6 = 642 </span>
<span>Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 </span>
<span>Distributive Property by allotting: 2(3) x 107 = 642<span>
</span></span>

What is the volume of the right rectangular prism?
Ivahew [28]
I saw the image that should have been included in this problem.

It was a rectangular prism. It can also be identified as a right prism because its bases are aligned one directly above the other and its lateral faces are rectangular.

The image has the following measurements:
length = 7 inches
width = 5 inches
height = 4 inches

volume = length * width * height
v = 7 in * 5 in * 4 in
v = 140 in³  Choice B i believe.
