Answer:
No.
Step-by-step explanation:
Take the second expression: 5(2 - 20)
To solve, you must distribute the 5 to all terms within the parenthesis:
5(2 - 20) = (5 * 2) - (5 * 20) = 10 - 100 = -90
On the other hand:
10 - 20 = -30
∴ the two expressions are not equivalent.
1/4 = 2/8... So:
3/8 - 2/8 = 1/8
Complete question :
How many cubic blocks of side length of 17 inch would it take to fill a rectangular prism with a length width and height of 3/7 inch 1/7 inch and 3/7 inch
Answer:
9 cubic blocks
Step-by-step explanation:
The volume of a rectangular prism is given as :
V = Length * width * height
V = 3/7 * 1/7 * 3/7 = 9 / 343 in³
The volume of block clube:
Take the cube of the side length :
(1/7)^3 = 1 / 343 in³
Number of cubic blocks required :
Volume of prism / volume of cube
9 / 343 ÷ 1 / 343
9 / 343 * 343 /1 = 9
Hence, 9 cubic cubes are needed to fill the rectangular prism
First of all, remember what the equation of a line is:
Where:
m=slope
b=y-intercept.
Given this information, we can start by plugging in what we know, we are given the slope which is 2 so we can fill that in, remember m=slope
To find b, think about what your (x,y) point means:<span>(14,3). When x of the line is 14, y of the line must be 3.
Because we were given the point (14,3)
</span>
We need to find the value of b. The 2 is already set and x and y are variables. We want the equation for the line that specifically passes through the given point (14,3).
<span>Plug in for x the number 14 and for y the number 3:
</span>(14,3).
y=mx+b or 3=2 × 14+b,
solving for b: b=3-(2)(14). b=-25.
<span>Plug that in for b:
</span><span>y=2x-25
<span>Final answer:
</span><span>y=2x-25</span></span><span><span>
</span></span>
