Answer:
92.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 92.5
Hope this helps!!
Answer:
20 mph
Step-by-step explanation:
First problem:
The new speed is 26 mph.
The old speed was x.
The new speed is 30% higher than the old speed.
1.3x = 26
x = 20
Answer: 20 mph
Second problem:
A number, perhaps a percent or a fraction, is missing from the problem.
4/17=x/100 》400\17=x 》x=23.5
M = Y / X
m = [1 - (-2) ] / [2 - (-2)]
m = (1+2) / (2+2)
m = 3 / 4
Using (2,1)
y - yo = m (x-xo)
y - 1 = 3/4 (x-2)
Or
(-2,-2)
y + 2 = 3/4 (x+2)
