Help Pls I need done soon as possible

Mathematics
1 answer:
Harrizon [31]3 years ago
5 0

Answer:

see explanation

Step-by-step explanation:

given the 2 equations

4x + y = 2 → (1)

- 2x + y = 5 → (2)

Eliminate the term in y by subtracting (2) from (1) term by term

(4x - (- 2x) + (y - y) = (2-5)

6x = - 3 ( divide both sides by 6 )

x = \frac{-3}{6} = - \frac{1}{2}

substitute this value into either (1) or (2) and solve for y

(1) : - 2 + y = 2 ( add 2 to both sides )

y = 4

solution is ( - \frac{1}{2}, 4)

Sam began with $45 in his bank account. He then saved $15 a week until he had $210 in his account. How many weeks did Sam save $
Natalka [10]

Answer: Sam had to save $15 for 11 weeks

Step-by-step explanation:

$45+$15w=$210

Subtract $45 on both sides:

$45-$45+$15w=$210-$45

$15w=$165

Divide 15 on both sides:

15/15w=165/15

w=11

Find the length of BC. <br> A.) 14<br> B.) 9<br> C.) 2<br> D.) 3
Vera_Pavlovna [14]

Answer:

A) 14

Step-by-step explanation:

BC is congruent to DC in saying this you can plug the equations to each other and solve for y and then put its back into the equation for BC to get the length.

3y+5=5y-1

subtract 3y from both sides --> 5=2y-1

add 1 to both sides --> 6=2y

now get y alone, divide by 2 by both side --> y=3

plug y in back to 5y-1 --> 5x3-1

15-1

BC = 14
