Answer:

x = -2

y = 7

Step-by-step explanation:

-x + 7y = 51

-x - 4y = -26

=> -x + 7y = 51

-x - 4y = -26

=> -x + 7y = 51

x + 4y = 26

=> 7y = 51

4y = 26

=> 7y + 4y = 51 + 26

=> 11y = 77

=> y = 7

=> -x + 7(7) = 51

=> -x + 49 = 51

=> -x = 51 - 49

=> -x = 2

=> x = -2

Lester’s car can go 15.4 miles on 1 gallon of gas. How far can he go on 0.7 gallon?

MAVERICK [17]

Answer:

He can go 10.78 miles

Step-by-step explanation:

This problem can be solve by creating a proportion, knowing that 15.4 miles is to one gallon the same as "x" miles (our unknown) is to 0.7 gallons. This can be set in math terms as the equation that relates these two ratios of miles per gallon:

$\frac{15.4\,miles}{1\,gallon} =\frac{x }{0.7\,gallon}$

and to solve for the unknown number of mile, we multiply both sides of the equation by "0.7 gallon" in order to isolate our unknown:

$\frac{15.4\,miles}{1\,gallon} =\frac{x}{0.7\,gallon}\\\frac{15.4\,miles\,*\,0.7\,gallon}{1\,gallon} =x \\x=10.78\,miles$

azamat

Answer:

(x + 2)²(x - 3)² = 0

Step-by-step explanation:

Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
