Answer:
5
Step-by-step explanation:
The easiest way is to subtract.
2.75 - (-2.25) = 2.75 + 2.25 = 5
Answer:
See explanation below
Step-by-step explanation:
Volume = (11)(10)(7) = 770 cubic centimeters
Surface area = (2)(10)(7) + (2)(11)(7) + (2)(11)(10) = 1774 square centimeters
b) Surface area (How much wax can cover the cube)
c) Volume (How much juice will be inside the cube)
answer:
9x
Step-by-step explanation:
there both like terms with means you can just and and subtract them.
Step-by-step explanation:
seeeee theeeeeee atttaaachmeeent
Angles (7x+17)° and (5x-5)° are consecutive interior angles, that means they add up to 180<span>°.
So we can make an equation to solve for x, which eventually will help us solve for y.
180</span> = (7x+17) + (5x -5)
re arrange that:
180 = 7x + 5x + 17 - 5
180 = 12x + 12
- 12 -12
168 = <span>12 x
</span> 12 12
14 = x
Now we will plug it into (5x - 5) to help us solve for y,
Angle (5x - 5) and (23y) are supplementary angles, meaning they equal to 180°.
<span> 180 = (23y) + (5(14) - 5)
180 = (23y) + (70 - 5)
180 = 23y + 65
- 65 - 65
<u>115</u> = <u>23y</u>
23 23
___ = y
Good luck!
