Answer:
see below
Step-by-step explanation:
4x - 4(30-2x)=24
4x-120+8x=24
12x=144
X=12
then substitute
2(12) + y =30
y=30-24
y=6
Answer:
4/63
Step-by-step explanation:
Multiple: 2/
5
* 2/
7
= 2 · 2/
5 · 7
= 4/
35
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(4, 35) = 1. In the following intermediate step, the fraction result cannot be further simplified by canceling.
In other words - two fifths multiplied by two sevenths = four thirty-fifths.
Multiple: the result of step No. 1 * 5/
9
= 4/
35
* 5/
9
= 4 · 5/
35 · 9
= 20/
315
= 4 · 5/
63 · 5
= 4/
63
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(20, 315) = 5. In the following intermediate step, cancel by a common factor of 5 gives 4/
63
.
In other words - four thirty-fifths multiplied by five ninths = four sixty-thirds.
Answer:
The answer is 60
Step-by-step explanation:
I am going to assume that A and a are the same variable. For future reference, a and A wouldn't be considered the same variable so be careful with that :)
We can first plug in 2 for a and 4 for b
4(2) + 2(4^2) - 2(2 - 3(4))
8 + 2(16) - 2(2 - 12)
8 + 32 - 2(-10)
8 + 32 - (-20)
8 + 32 + 20
60
