Jane has half as much as Elaine at first. The answer is 12, but I honestly just kept using random numbers. After spending 4, Jane has 8 and Elaine has 20.(12 times 2) - 4
Step-by-step explanation:
I'm sorry if my terminology isn't correct because I've learnt it slightly differently, but what I'm assuming is this:
For A, you can rewrite the integers as 28-15+22 as a + and a - next to each other result in a subtraction.
For B, you simply do 15+22 is 37 and 28-37 is -9 due to BIDMAS (or PEDMAS if you're American).
I'm not sure if this is correct but you would put it into an equation while you solve for X. so 0.75x=150 or equivalently would be like (3/4)x=150 Then after that you would divide both sides by 0.75 or 3/4
<span>{x=2+y
{-6x-6y=-12
-6(2+y) -6y = -12
-12 - 6y - 6y = -12
-12y = -12 + 12
-12y = 0
y = 0
x = 2 + y = 2 + 0 = 2
Answer: x=2, y=0</span>
Answer:
The correct answer is,
The quotient is 3x - 4
Step-by-step explanation:
It is given that,
n(x) = 6x^2 + x − 7
a(x) = 2x + 3
<u>To find n(x) by a(x)</u>
n(x) = 6x^2 + x − 7
a(x) = 2x + 3
n(x) by a(x). can be written as,
<u> 3x - 4 </u>
2x + 3 ) 6x^2 + x − 7
<u> 6x^2 + 9x</u>
-8x - 7
<u> -8x - 12</u>
5
Therefore quotient = 3x - 4
