okay since the first step is parenthesis, the next step would be exponents but you have none so you skip to multiplication, then you divide
divide is your answer
Step-by-step explanation:
6000
your answer is 6000
Answer:
step 3: he should have divided both sides by -7
The number is 6.25.
We will set up an equation for this. Let x be the unknown number. Subtracting 1.05 from it gives us
(x-1.05)
Multiplying the difference by 0.8 would give us
0.8(x-1.05)
Adding 2.84 to the product would give us
0.8(x-1.05)+2.84
Dividing the sum by 0.01 would give us
[0.8(x-1.05)+2.84]/0.01 = 700
We will start working backward, cancelling the division by 0.01 first by multiplying:
([0.8(x-1.05)+2.84]/0.01)*0.01 = 700*0.01
0.8(x-1.05)+2.84 =7
Subtract 2.84 from both sides:
0.8(x-1.05)+2.84-2.84 = 7-2.84
0.8(x-1.05) = 4.16
Use the distributive property on the left side:
0.8*x - 0.8*1.05 = 4.16
0.8x - 0.84 = 4.16
Add 0.84 to both sides:
0.8x - 0.84+0.84 = 4.16+0.84
0.8x = 5
Divide both sides by 0.8:
0.8x/0.8 = 5/0.8
x = 6.25
Answer: 34
Step-by-step explanation:
<u>Given expression</u>
[3 - (3 · 3) + 33 ÷ 3] × 4 · 5 / 10 - 2 · 3
<u>Simplify by parentheses in the bracket</u>
=[3 - 9 + 33 ÷ 3] × 4 · 5 / 10 - 2 · 3
<u>Simplify by multiplication</u>
=[3 - 9 + 33 ÷ 3] × 20 / 10 - 6
<u>Simplify by division</u>
=[3 - 9 + 11] × 10 - 6
<u>Simplify by bracket (addition/subtraction)</u>
=[-6 + 11] × 10 - 6
=[4] × 10 - 6
<u>Simplify by multiplication</u>
=40 - 6
<u>Simplify by subtraction</u>
