Use PEMDAS (order of opperations)
P - parenthesis
E - Exbonents
M - Multiply
D - divide
A -add
S - subtract
You go in order except for the divison and multiplication you go from Left to right
Ex) 45/15(5x2)
Since thats in parenthsis yoh multiply it =10 the. Divide 45/15= 3 then multiply 10x3=30

Combine like terms: 4+7x=11
subtract 4 on both sides: 7x=7
divide by 7 on both sides: x=1

Sandra's printer can print 5 pages in 2/3 of a minute (40s). Show different ways to determine how many pages her printer can pri

Ne4ueva [31]

Answer:

$7\frac{1}{2}$ pages

Step-by-step explanation:

Method 1: Working with minutes

Let us assume that, Sandra's printer can print x pages in 1 minute.

Then we can write the equation:

$x:1=5:\frac{2}{3}$

We can rewrite the ratios as a fraction.

$\frac{x}{1}=\frac{5}{\frac{2}{3}}$

This simplifies to

$x=\frac{15}{2}$

$x=7\frac{1}{2}$

Method 2: Working with seconds

If 5 pages corresponds to 40 seconds, then we can write: $5:40$

Let y corresponds to 60 seconds (1 minutes).

Then:

$y:60=5:40$

We rewrite as fraction:

$\frac{y}{60}=\frac{5}{40}$

Multiply both sides by:

$y=\frac{5}{40}\times 60$

$y=\frac{300}{40}$

$y=\frac{15}{2}$

$y=7\frac{1}{2}$

What is the height of a rectangle when I base is 8 ft and the area is 30 ft

ZanzabumX [31]

To do this you have to fill in the equation $base*height=area$ , but you don't know the height, so we'll use $h$ for height. Plugging in the numbers you gave me, the equation is: $8*h=30$ . To solve this, we need to find $h$ . To find height you do $\frac{area}{base}$ . Doing this, we get $h$ = 3.75 ft.

Hope this helped!
