Step-by-step explanation:
-2(3x-12)+4-13
=-6x+24+4-13=-7x-15
=6x-15
4(5x-1)+8x-20=20x-4+8x-20
=28x-24
So this is ur solution.
But if u wnt to solve these eq. together thn it will be:-
6x-15=28x-24
6x-28x=-24+15
-22x=-9
x=22/9=2.44
Hope u like it.
While the scale I know it’s right
Answer:
see below
Step-by-step explanation:
If suffices to look at the last term. It must simplify to 4/(3w²), so the exponents of z must match in numerator and denominator, and the ratio of constants must reduce to 4/3.
The exponents of z have the right values in choices B and D, but the ratio of constants only matches in choice D. Looking at the rest of choice D, we see that we can factor 6w²z² from both numerator and denominator, then factor 2 from the remaining numerator to make it match the desired form.
Answer
Expressions 4(x+5) and 5(x+4) are Equivalent
Expressions 5(2m+2) and 10m+10 are not equivalent
Step-by-step explanation:
Heres why,
4(x+5) and 5(x+4)
4 times x =4x, so multiply 4x by 5 which should give you 20.
and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.
5(2m+2) and 10m+10
times 5 to 2m to get 10m and times 10m by 2 to get 20.
10m+10 = 1 which they are not equivalent
