Answer:
(-12,2)
Step-by-step explanation:
2x + 4y = -16
2y - x = 16
Multiply the bottom part by 2.
2x + 4y = -16
4y - 2x = 32
Add the equations and the answers to the equations up, and they will equal each other.
(2x + 4y) + (4y - 2x) = -16 + 32
8y = 16
y = 2
Plug y = 2 to the 2nd equation.
2*2 - x = 16
4 - x = 16
Subtract 4 from both sides.
-x = 12
Multiply both sides by -1.
x = -12
There are 16 ounces in a pound. 16*5 is 80. If you do 80 divided by 5 you get 16. Therefore, she can make 16 batches. If there are 6 ornaments in a batch, you do 16*6 which is 96.
Answer:
<u>3 stamps were left over</u>
Step-by-step explanation:
<u>Division</u>
When a number m divides evenly by n the remainder is 0. For example, 120 divides exactly by 30 because 120/30=4 and the remainder is 0.
But 120 does not divide exactly by 50 because 120/50 = 2 and leaves a remainder of 20.
Jeff divided his 1,200 stamps equally among 7 stamp albums. If the division of 1,200 by 7 was exact, there won't be any stamp left over. Let's test it.
1,200/7 is 171.4, obviously is not exact, thus There were stamps left over.
How many?
Multiply the lower integer of division 171 by 7 to get: 171*7 =1,197. This means that 1,200-1,197= 3 stamps were left over
❦Okay lets start!!!❦ So we have to find a common denominator of 3/4 and 5/8.
I guess we can start will 3/4
3/4 times 2 =
6/8 ❣
Okay so we have 6/8 and 5/8
But if you want them to be a different one we can do
3/4 times 4 which is =
12/16❣
And now 5/8 times 2
which is
= 10/18❣
❦ There's so much ways to do this!!! I hope I helped ❦
