Answer:
Multiply the second equation by -3 to get -3x - 9y = -30.
Step-by-step explanation:
When eliminating, you need to find a term with the negative of that term to combine so that they cancel each other out. An example would be 3x in the first equation and (-3x) in another equation so that when added, it becomes: 3x-3x = 0.
In the second equation, you see that there is already an x there and you just need to make it become (-3x). Thus, you multiply the entire second equation by -3 to make -3x. Once you have done that, you can combine the two equations and eliminate 3x from the first equation.
3x + 5y = 30
-3x - 9y = -30
3x + 5y -3x - 9y = 30 + (-30)
0 - 4y = 30 - 30
-4y = 0
<em>You can find y and then x later on from here. </em>
Yes because if you write it it's twenty nine out of one hundred
Answer:
Hello! answer: e = 108 d = 32 f = 40 because
108 + 108 + 32 + 32 + 40 + 40 = 360 Hope this helps!
Yes. Kevin can carry the basket 5 ft. Rachel can carry it 3 feet more than Kevin (5+3=8). Daniel can carry the basket half the length of Rachel (8/2=4). The total distance they can carry the basket is 5+8+4=17. 17 is greater than 15, so yes they can carry it 15 feet.
Answer:
, 12, 
, 10
Step-by-step explanation:
so
= 10
12
= 10.66
and 10
Because saying 5 over 1/2 is saying 5 divided by 1/2 which is the same as saying 5 * 2
8 over 3/4 is 8 divided by 3/4 which is 8 * 1.33.
A fraction is division. If you mean 5 and 1/2 as well as 8 and 3/4 then remove 5 and 1/2 from the answer.
