Answer:

Step-by-step explanation:

-5x-y=5 since its substitution, take the equation that has the variables on

x=7y-1 opposite sides(x-7y-1) and sub in whats on the opposite side of the

-5(7y -1)-y=5 equal sign (7y-1) in for the x variable in the first equation

-35y+5-y=5. then you distribute the -5 to every value in the parenthesis

-36y=0 then you isolate the remaining variable on one side

y=0 then divide until the variable has no coefficiant

-5x-0=5 then you plug that value back in to the first equation

-5x=5 isolate the variable again

x=-1 then divide again. your y value is 0 and your x value is -1

Find the value of 2. 78° 1200 15° B

andrew11 [14]

I tried but see if this helps you In algebra, it is easy to find the third value when two values are given. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.

A parking lot has 916 parking spaces that are shaped like parallelograms. The base of each space is 10 feet, and the height of e

dmitriy555 [2]

The area of a parallelogram is $A=bh$

$A=10(18.5) \\ A=185$

I am assuming you're asking for the entire parking lot, so you would have to multiply the above area by 916

$185(916) = 169,460 ft^{2}$

So the answer is (D)
