The answer is 280 because if you multiply 400 by .3 you get 120 and if you subtract 120 from 400 you get 280
Answer:
x+(x+4)=52
Step-by-step explanation:
Let's name the smaller number x.
The greater number would then be (x+4).
<em>The sum of two numbers means we are adding them together.</em>
<u>The equation we could then set up would be:</u>
x+(x+4)=52
<em>Now we can solve the equation to find the two numbers if needed.</em>
<u>Here is how:</u>
x+x+4=52
Combine like terms.
2x+4=52
Subtract 4 from both sides.
2x=48
Divide both sides by 2
x=24
The smaller number is 24.
24+4=28
The larger number is 28.
Answer:
70%of x = 63
70/100 × x = 63
x=63×100/70
x=90
Step-by-step explanation:
The answer is 9.
6x4=24
?x4=36
Answer:
w = -1
Step-by-step explanation:
- w-5-4= -8-6w+8w ⇒ simplify
- w - 9 = - 8 + 2w ⇒ add 9 - 2w to both sides
- w - 2w = - 8 + 9 ⇒ simplify
- -w = 1 ⇒ multiply both sides by -1
- w = -1 ⇒ answer
