let their age be x and y

x=y.......1st equation

<u> </u><u> </u><u> </u><u> </u>2

now,

product of their age

x+y=63

<u>y</u><u> </u>+y=63 (putting the value of x=y/2)

2

<u>3</u><u>y</u><u> </u>=126

y=<u>1</u><u>2</u><u>6</u>

y=42

hence,

age of jessica is y =42.

Write the expression in repeated multiplication form. Then write the expression as a power. (-8)^3*(-8)^4 The expression in repe
Makovka662 [10]

Given:

The expression is

(-8)^3\cdot (-8)^4

To find:

The expression in repeated multiplication form and then write the expression as a power.

Solution:

We have,

(-8)^3\cdot (-8)^4

The repeated multiplication form of this expression is

=[(-8)\cdot (-8)\cdot (-8)]\cdot [(-8)\cdot (-8)\cdot (-8)\cdot (-8)]

=(-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)

Clearly, (-8) is multiplied seven times by itself. So,

=(-8)^7

Therefore, the repeated multiplication form of the given expression is (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8) and the expression as single power is (-8)^7.

Find the value of x.
mylen [45]

Answer:

d

Step-by-step explanation:

7x + 2 and 10x - 9 are same- side interior angles and sum to 180° , that is

7x + 2 + 10x - 9 = 180

17x - 7 = 180 ( add 7 to both sides )

17x = 187 ( divide both sides by 17 )

x = 11 → d

Can you please help me on -5(x+2)=-(-5x+1)-x
PilotLPTM [1.2K]

Answer:

x = -1

Step-by-step explanation:

<u>Step 1:  Distribute</u>

-5(x + 2) = -(-5x + 1) - x

-5x - 10 = 5x - 1 - x

<em>-5x - 10 = 4x - 1</em>

<em />

<u>Step 2:  Solve for x</u>

-5x - 10 + 5x = 4x - 1 + 5x

-10 + 1 = 9x - 1 + 1

-9 / 9 = 9x / 9

<em>-1 = x</em>

<em />

Answer:  x = -1
