Answer:
Step-by-step explanation:
The first 9 stands for 90,000 and the second for 9 000 so the first 9 is worth
90,000 / 9,000 equals 10 times the second one.
Hello, there!
88 = 4a + x
Rewrite the equation as <span><span>4a+x=88
</span><span>
4a+x=88
</span></span>Since <span><span>4a</span></span> does not contain the variable to solve for, move it to the right side of the equation by subtracting <span><span>4a </span></span>from both sides.<span>
4a + x = 88
-4a -4a
Therefore, x = 88 - 4a
Our answer is x = 88 - 4a
We can't simplify this any further, as we have no value of a.
I hope I helped!
Let me know if you need anything else!

Step-by-step explanation:
Problem 1
<h3>Answer: 3 slices</h3>
-------------------------------------
Explanation:
1/4 = 0.25
She eats 25% of a pizza in 12 minutes
We can form the ratio 0.25/12
This ratio is then set equal to x/18. The value of x represents what proportion of the pizza is eaten after 18 minutes.
Solve for x
0.25/12 = x/18
0.25*18 = 12x ..... cross multiply
4.5 = 12x
12x = 4.5
x = 4.5/12
x = 0.375
x = 375/1000
x = (125*3)/(125*8)
x = 3/8
She ate 3/8 of the whole pizza in 18 minutes.
There are 8 slices in a full pizza, so (3/8)*8 = 3 means that she ate 3 slices.
Or you could say "eating 3 slices out of 8 total means she ate 3/8 of the full pizza".
===================================================
Problem 2
<h3>Answer:
5/8</h3>
-------------------------------------
Explanation:
We'll use the same idea as before. Though now we're setting 0.25/12 equal to x/30
Solving for x leads to...
0.25/12 = x/30
0.25*30 = 12x
7.5 = 12x
12x = 7.5
x = 7.5/12
x = 0.625
x = 625/1000
x = (125*5)/(125*8)
x = 5/8
She will eat 5/8 of the pizza in 30 minutes.
