Answer:

<u>y = 6 x=8</u>

Step-by-step explanation:

(3х + 5y = 54)-2 times by -2

6х +4y = 72

-6х + -10y = -108 now combine the equations

6х + 4y = 72

-6y = -36 now divide

y = 6

Plug 6 in 6х +4 * 6 = 72

x=8

Answer:

Step-by-step explanation:

Question 1: C

1 multiplied by 5 = 5

1 plus 5 = 6

So you get: (x+5)(x+1) which means x = -5 or -1

Question 2: B

2 multiplied by -4 = - 8

2 plus -4 = -2

So you get: (x-4)(x+2) which means x = 4 or -2

1. A. 1908. In the first year, (a year is 12 months), he paid 159 a month so 159 times 12 is 1908. (You are correct on this one)

2. A. 1908. In the second year, (again a year is 12 months), he paid 159 a month so 159 times 12 is 1908.

(Btw : there would be a third year 36/12=3. He would also pay another 1908 in the third year. To get your answer for number three either do the stragety I wrote for it or do 1908+1908+1908+2399=8123 or (1908•3)+2399.

3. C. <span>8123. </span>Well 159 times 36 is 5724 plus 2399 and get <span>8123. That is the total cost of the lease.

Hoped I helped!

The article is 10 lbs...so 20 of them = (10 * 20) = 200 lbs
the box is 1/2 lb....so 20 of them = (1/2 * 20) = 10 lbs
the freight container is 15 lbs

for a total of : 200 + 10 + 15 = 225 lbs <==
