Answer:
<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>
Step-by-step explanation:
Given the expression
- 2 (x + 3) = - 10
The first step in solving the expression is to multiply both sides by -1/2 as shown;
-1/2(-2)(x+3) = -1/2(-10)
(x +3) = 1/2(10)
x + 3 = 5
x = 5-3
x = 2
Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)
Answer:
<h2>A</h2>
Step-by-step explanation:
Exponents are representations of repeated multiplication.
For example: 5³ = 5 x 5 x 5 or 125. If we want to compare values, we must evaluate each expression and then compares the final values for each.
3⁶ = 3 x 3 x 3 x 3 x 3 x 3 = 729
6³ = 6 x 6 x 6 = 216
729 > 216
We can immediately notice that 3⁶ is much larger than 6³
Answer:
same time , 12 minutes
Step-by-step explanation:
'A' can eat 1÷6 pizza in 2 minutes
Therefore, 'A' can eat full pizza in 6×2 minutes=12 minutes
'B' can eat 1÷4 pizza in 3 minutes
therefore, 'B' can eat full pizza in 3×4 minutes=12 minutes
So, Both 'A' and 'B' will finish at same time.
Answer:
Scale factor is 2.5
Value of X: 27.5
Value of y: 12
Value of z: 7.5
Step-by-step explanation:
Okay so. A scale factor is the number by which the shape is increasing, or decreasing by. Like if a square went from 5 cm on all sides to 10 cm on all sides, the scale factor would be 2. This shape has been rotated, so you want to rotate it back so the sides match up when you compare them. The only two sides with a number (without a variable) are 8 and 20, for 8 to be able to get to the number 20, it had to be multiplied by 2.5. To get all the other sides answers, you need to multiply any numbers by 2.5 if it the shape of the left, if it is the shape on the right you need to divide it by 2.5.
