(5у — 4)° Зу (2x + 13)°

Mathematics
1 answer:
ale4655 [162]3 years ago
7 0

Answer:

No Solution.

Step-by-step explanation:

Equality equation:

— 2y – Зу +8 = 8 — 5у – 12  (Given)

-5y + 8 = -4 - 5y (distributive property of equality)

-5y = -12 - 5y (subtraction property of equality)

= -12 (addition property of equality)

when you add 5y on both sides it cancels the 5y out, it's no solution.

Hailey and Kacie are selling candles to raise money. • Hailey is selling candles for $4 each and has already raised $160. • Kaci
marysya [2.9K]

Answer:

The number of candles each girl needs to sell so that the total amount raised is the same for both is

<em>Hailey </em>70 candles

<em>Kacie  </em>40 candles

Step-by-step explanation:

Let

x------> the number of candles sold

y----> total amount raised          

we know that

<em>Hailey's equation</em>

y=4x+160 -----> equation A

Please note that Hailey has already raised $160, so he has sold 40 candles.

<em>Kacie's equation</em>

y=7x+70 -----> equation B

Please note that Kacie has already raised $70, so he has sold 10 candles.

equate equation A and equation B solve for x

4x+160=7x+70

7x-4x=160-70

3x=90

x=30\ candles

The number of candles each girl needs to sell so that the total amount raised is the same for both is

<em>Hailey</em>

  40+30=70 candles

<em>Kacie</em>

  10+30=40 candles
