Simplify 3/4(1/2×-12)+4/5​
Wittaler [7]

Answer: \frac{3}{8}x-\frac{41}{5} or  \frac{3}{8}x-8\ \frac{1}{5}

Step-by-step explanation:

Given the following expression:

\frac{3}{4}(\frac{1}{2}x-12)+\frac{4}{5}

You can follow these steps in order to simplify it:

1.  You need to apply Distributive property:

=\frac{3}{8}x-9+\frac{4}{5}

2. And now you must add the like terms. Then:

=\frac{3}{8}x-\frac{41}{5}

Therefore you get the following answer:

\frac{3}{8}x-\frac{41}{5} or  \frac{3}{8}x-8\ \frac{1}{5}

Is y=7.5x a proportional relationship and why
DerKrebs [107]
Direct Proportion functions look like this:

y=kx

'k' is the constant of proportionality and in this case its 7.5 or 15/2.

--------------------------------------------

When x=1, y=7.5
When x=2, y=15
When x=3, y=22.5

Therefore y is directly proportional to x.

--------------------------------------

DIRECT PROPORTION EXPLAINED:

Say a football costs £7.50. If you buy one football you'll have to pay out £7.50, but if you you buy two footballs you'll have to pay out £15.00. Therefore the cost of the football(s) is directly proportional to the amount of footballs you buy. C=cost, f=football(s) and C<span>∝f, therefore C=kf, but as k=7.5, C=7.5f.

INVERSE PROPORTION EXPLAINED:

If it were to take 8 hours for one bricklayer to set up a wall, how long would it take for two bricklayers to set up a wall? The answer in this case would be 4 hours.

T=time to set up a wall
b=bricklayer(s)

Therefore T</span><span>∝1/b, and T=k/b. In this case k=8 so T=8/b.

When b=1, T=8.
When b=2, T=4.

We'd say that the time it would take for bricklayers to set up a wall would be inversely proportional to the amount of bricklayers available.</span>

PLEASE HELP ME I AM TAKING A TEST AND I NEED HELP!!!
zhannawk [14.2K]
Part A.
y=4x+3

Part B.
11=4x+3
8=4x
2=x
2 dollars

Part C.
4(3)+4(2)=12+8=20

It would be enough if there is no sales tax.

Hope this helps!
