Step-by-step explanation:
y=7x-10
Answer:
multiply both sides by 8 then divide by -3
or in one step divide both sides by (-3/8) which is the same as multiplying by
(-8/3)...
-3p = 72
p = -24
Step-by-step explanation:
Gallons of water drank in 4 days = 120
Gallons of water drank in a day = 120/4
= 30
Gallons of water drank in 28 days = 30 × 28
= 840
The answer is: " 27 " .

-Edit -- Note the following property of exponents : "quotient rule" of exponents:
_____________________________________________
Given that "a" and "b" are positive integers; and that "x" is a real number greater than "zero";
____________________________________________
If a <span>≥ b , then:
x</span>ᵃ /xᵇ = x⁽ᵃ ⁻ ᵇ⁾ ;

Answer:
Step-by-step explanation:
x=0.5, y=7
x=1, y=14
x=1.5, y=21
x= 2, y=28
Let’s take the first equation.
y = 14x
y = 14(0.5) = 7
When x is 0.5, y is 7.
y = 14(1) = 14
When x is 1, y is 14.
y = 14(1.5) = 21
When x is 1.5, y is 21.
y = 14(2) = 28
When x is 2, y is 28.
