Answer:
71, 72, 73, 74 . for details, check below
Step-by-step explanation:
a) Let's assume that among the four consecutive numbers, the first one is x,
so, the four consecutive numbers should be:
- x
- x+1
- x+2
- x+3.
According to the question,
(x) + (x + 1) + (x + 2) + (x + 3) = 290
<h2>
b)</h2>
(x) + (x + 1) + (x + 2) + (x + 3) = 290
4x + 6 = 290
4x = 284
x = 284÷ 4
x = 71.
So, the numbers are,
71, 72, 73, 74
Answer:
x = 50
Step-by-step explanation:
Let x be the original price.
He got 30% off
The discount is .30x
Subtract this from the original price to get the price he paid
x - .30x = price he paid
.70x = price he paid
.70x = 35
Divide each side by .7
.70x/.7 = 35/.7
x=50
