Answer:
85x
Step-by-step explanation:
Add 4 and 3 . 5 x ( 28 − 4 − 1 * 7 ) Multiply − 1 by 7.
5 x ( 28 − 4 − 7 )
Simplify the expression. Subtract 4 from 28.
5 x ( 24 − 7 )
Subtract 7 from 24.
5 x * 17
Multiply 17 by 5.
85 x
Since she has already ridden 7 miles out of 31 miles,
remaining miles to be ridden
= 31 - 7
= 24 miles
Let x be the number of miles she has to ride in each of the 4 days left.
4x = 24
x = 6

Answer:
20
Step-by-step explanation:
→ First find the value of x and y
x + y = 5
x - y = 4
→ Add the equations to cancel out the y's
2x = 9
→ Divide both sides by 2 to find the value of x
x = 4.5
→ Substitute x = 4.5 back into x - y = 4 to find the value of y
4.5 - y = 4
→ Minus 4.5 from both sides to isolate -y
-y = -0.5
→ Multiply everything by -1
y = 0.5
→ Substitute x = 4.5 and y = 0.5 into x² - y²
4.5² - 0.5² = 20.25 - 0.25 = 20
