Answer:
1)42
2)400
3)$2000
Step-by-step explanation:
Q1)
- 35% = 35/100 = 7/20 (simplify)
- (7/20)×120 = 42
Q2)
- Let number = $
- 60% = 60/100 = 3/5
- (3/5)×$ = 240
$ = 240 ÷ (3/5)
= 240 x (5/3)
= 400
Q3)
- Let number = #
- 40% = 40/100 =2/5
- (2/5)×# = $800
# = $800 ÷ (2/5)
= $800 × (5/2)
= $2000

The two equations given in the question are
y = - x + 5
and
5x + 2y =14
Now we will have to put the value of y from the first equation in the second equation and then calculate.
5x + 2y = 14
5x + 2(-x + 5) = 14
5x - 2x + 10 = 14
3x = 14 - 10
3x = 4
x = 4/3
Now we have to put the value of x in the first equation for determining the value of y
y = - x + 5
= - (4/3) + 5
= (15 - 4)/3
= 11/3
So the value of x is 4/3 and the value of y is 11/3.
Answer:
The answer is m = 150
Step-by-step explanation:
A - 700 = 250 + 3m
B - m = 150 miles
C - m = 150
3(150) + 250 = 700
↓ ↓ ↓ ↓ ↓
450 + 250 = 700
