Answer:

DG = 17

Step-by-step explanation:

DG and EF are similar so sides are same.

2x - 7 = x + 5

2x - x = 5 + 7

x = 12

So DG = 2x - 7

           = 2(12) - 7

           = 24 - 7

           = 17

Please help with the following problem asap!!
umka21 [38]

Answer:

8^7

Step-by-step explanation:

\dfrac{8^{15}}{8^7 \cdot 8} =

Remember that 8 = 8^1.

= \dfrac{8^{15}}{8^7 \cdot 8^1}

When you multiply powers with the same base, add the exponents. Do this in the denominator.

= \dfrac{8^{15}}{8^{7+1}}

= \dfrac{8^{15}}{8^{8}}

When  you divide powers with the same base, subtract the exponents.

= 8^{15-8}

= 8^7

Hiii! Plzz help!

1/6 of a minute is also 1/6*60 which equals to ten seconds. To find how many words she can type in 120 seconds, we need to divide 120 by 10 and then multiply the rate. 120/10 = 12, and then we multiply 12 by 8. 12*8=96

Given: x - 6 1/3≤ 1 1/2 Choose the solution set. a. {x | x ∈ R, x ≤ 7 5/6} b. {x | x ∈ R, x ≤ 7 2/5} c. {x | x ∈ R, x ≤ 5 1/6}

x-6\frac{1}3\leq1\frac{1}2

Add 6 1/3 to each side.

x\leq1\frac{1}2+6\frac{1}3

To add together the 1/2 and the 1/3, change them to a common denominator.

x\leq1\frac{3}6+6\frac{2}6

x\leq7\frac{5}6

\boxed{\{\ x\ |\ x\in\mathbb{R},\ x\leq7\frac{5}6\}}
