Answer:
arithmetric
Step-by-step explanation:
the difference is so simple
Total number of marbles = 70 + 120 + 60 = 250
Prob of green = 60/250
Reduced fraction = 6/25
Percentage = 24%
Answer:
<u>A. (7x)³ + 8 ⇔ 8 added to the product of 7 and x cubed</u>
<u>B. 7x³ + 8 ⇔ 8 added to cube of 7x</u>
<u>C. 7 (x + 8)³ ⇔ 7 times the cube of the sum of x and 8</u>
<u>D. (7x + 8)³ ⇔ the cube of the sum of 7x and 8</u>
Step-by-step explanation:
1. Let's drag the tiles to the correct boxes to complete the pairs.
A. (7x)³ + 8 ⇔ 8 added to the product of 7 and x cubed
The second tile was already given and solved, however we're copying it.
B. 7x³ + 8 ⇔ 8 added to cube of 7x
C. 7 (x + 8)³ ⇔ 7 times the cube of the sum of x and 8
We use the expression 7 times because number 7 is multiplying the sum inside the parenthesis.
D. (7x + 8)³ ⇔ the cube of the sum of 7x and 8
Answer:
v=12
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-4*v-5-(-53)=0
Pull out like factors :
-4v + 48 = -4 • (v - 12)
Solve : -4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : v-12 = 0
Add 12 to both sides of the equation :
v = 12
To check yourself:
-4(12)-5 = -53
