The answer is 2,000 because 28 is lower than 50.
Answer:
x=100
Step-by-step explanation:
(2x+8)+(71-x)=180
2x+8+71-x=180
x+80=180
x=180-80
x=100
Answer: 1.2 Miles
Step-by-step explanation:
Add total miles together: 275 + 357.5 = 632.5 miles total
Add total hours together: 212 + 314 = 526 hours total
Divide total miles driven by total time:
632.5 ÷ 526 = 1.20247147843 miles an hour
Perimiter is 20ft
width is
what
do you mean the width is 8 feet less than the length? or 4ft less?
anyway
P=2(L+W)
20=2(L+W)
divide by 2
10=L+W
and
L=10-W
width is 4ft less than length (I assuming)
W=-4+L
repalce W with -4+L
L=10-(-4+L)
L=10+4-L
L=14-L
2L=14
L=7
W=-4+L
W=-4+7
W=3
it is 7ft by 3ft
Answer:
Equation is 
0.125 gallons of the 35% acid solution Eli should add.
Step-by-step explanation:
Given : Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution.
To find : Equation can you use to determine how many gallons of the 35% acid solution Eli should add?
Solution :
Let x be the gallons of the 35% acid solution.
According to question,
For 0.5 gallon of a 10% acid solution = 
For x gallon of a 35% acid solution = 
For (0.5+x) gallon of a 15% acid solution = 
The equation form is

Solving the above equation,




Therefore, 0.125 gallons of the 35% acid solution Eli should add.
The equation is
