u=5/4

Explanation:

distribute and simplify right side of equation

3= 28−14u −6u

3=28−20u

subtract 28 from both sides

3−28=−20u

−25=−20u

divide both sides by

−20/ −25 = u ⇒ u =54

Answer:

5/4

Step-by-step explanation:

, open the bracket

3=28-14u-6u

Collect like terms

3-28=-14u-6u

-25 =-20u

Divide both side by -20

u=-25/-20. Minus sign will cancel each other and reduce to the lowest term

u=5/4

Help me with this lol value of( 2^3)^2

ss7ja [257]

Answer:

Step-by-step explanation:

first, we'll start with the value inside the parenthesis, which is 2³

2³ means to multiply 2 by itself 3 times

so it would be

2×2×2=8

which then means that the expression is now (8)²

now we need to do (8)², which is to multiply 8 by itself twice

8*8=64

hope this helps!

Sara drove 96 miles on 3.2 gallons of gas. How many miles can Sara drive on 12.5 gallons of gas

Blababa [14]

Answer:

375 miles

Step-by-step explanation:

Create a proportion where x is the number of miles she can drive on 12.5 gallons of gas:

$\frac{96}{3.2}$ = $\frac{x}{12.5}$

Cross multiply and solve for x:

3.2x = 1200

x = 375

So, with 12.5 gallons of gas, Sara can drive 375 miles
