10x - 3 = x + 2 + 2x - 1
10x - 3 = 3x + 1
-3x on both sides
7x - 3 = 1
-1 on both sides
7x - 4
(Check 7x - 4 by adding them all up to equal 10x - 3)
x + 2 + 2x - 1 + 7x - 4 = 10x - 3
combine liked terms
10x - 3 = 10x - 3
Answer:
D) 7x - 4
If you would like to solve 26/57 = 849/5x, you can do this using the following steps:
<span>26/57 = 849/5x /*(5x)
</span>26/57 * (5x) = 849 /*57
26 * 5x = 849 * 57 /26
5x = 48393/26 /5
x = <span>48393/(26*5)
x = 372.25
The correct result would be </span><span>372.25.</span><span>
</span>
Answer:
He subtracted incorrectly
Step-by-step explanation:
You multiply 42.75 x 4 and get 171. Then you add 171+52.45=223.45 and then you subtract 223.45-18=205.45 and then you multiply 223.45 x .3333 = 68.3265 or 68.33 (rounded)
It will be cost $ 42.39 for 27 slices of pizza
<h3>
Further Explanation</h3>
A slice of pizza = $1.57
27 slices of pizza = the number of pizza x price/slice
= 27 x 1.57
We are going to use standard algorithm to solve this multiplication
1.57 ⇒ 2 decimal places
<u> 27</u> x ⇒ 0 decimal place
1099
<u> 314 </u>+
42.39 ⇒ 2 decimal places
In decimal number multiplication, the process is the same with the whole number multiplication. Only always remember when to put the decimal point in the answer.
