Solve each equation. Explain your method.8.88=4.44(x−7)

omeli [17]

8.88=4.44(x−7)

write the equation

8.88 - 4.44=(x−7)

Transfer 4.44 to other side and it's sign changes from positive to negative

4.44=(x−7)

After subtracting we will get result as 4.44

(x−7) = 4.44

Arrange the equation as variable always comes at left side.

x−7 = 4.44

open brakets

x = 4.44 + 7

transfer 7 to other side and it changes from - to + sign

x = 11.44

Convert 11.42424242 to a rational expression in the form of a/b , where b ≠ 0.

TiliK225 [7]

11.424242
isolate the repeating part
11+0.424242

focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242

subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99
$x=\frac{42}{99}$

so
$11.\overline{42}=11 \space\ \frac{42}{99}$

PLEASE HELP ASAP

PIT_PIT [208]

Answer:

27 cubic feet

Step-by-step explanation:

A pyramid is always 1/3 of a cube when it has the same base as a pyramid.

ALSO, thats why the volume of a square pyramid has 1/3 in it.

So, if the volume of this pyramid is 9 cubic feet then:

9 x 3 = 27 cubic feet

Hope this helps!
