PLS HELP ME ASAP FOR ALL 6!! (MUST SHOW WORK!!!) +LOTS LOTS OF POINTS!!!

Sedaia [141]

1. -4a-6=-12
add 6 to both sides
-4a-6+6=-12+6
-4a=-6
Divide by -4
$a= \frac{6}{4} = 1 \frac{1}{2}$

2. $\frac{3}{5} z- \frac{1}{4} = \frac{17}{20}$
add $\frac{1}{4}$ to both sides but you will need to make a common denominator on the right
$\frac{3}{5} z- \frac{1}{4} + \frac{1}{4} = \frac{17}{20} + \frac{5}{20}$
$\frac{3}{5}z= \frac{11}{10}$
Divide by $\frac{3}{5}$ which means multiply by the <span>reciprocal</span>.
$\frac{3}{5}* \frac{5}{3} z= \frac{11}{10} * \frac{5}{3}$
$z= \frac{55}{30} =1 \frac{5}{6}$

3. $2 \frac{1}{2}(e-1 \frac{3}{4})=5 \frac{1}{2}$
Distribute
$2 \frac{1}{2} e-4 \frac{3}{8} =5 \frac{1}{2}$
Subtract
$2 \frac{1}{2} e=1 \frac{1}{8}$
Divide
$e= \frac{9}{20}$

4. 3w+7=20
Subtract
3w=13
Divide
$w= \frac{13}{3} = 4 \frac{1}{3}$

5. -.2p+.4=-1.2
Subtract
-.2p=-1.6
Divide
p=8

6. $\frac{y}{4} - \frac{3}{5} = \frac{18}{20}$
Add, made sure you change to common denominator first
$\frac{y}{4} = 1 \frac{1}{4}$
Multiply by 4
y=5

Hope that helps

Max can mow a lawn in 45 minutes. Jan takes twice as long to mow the same lawn. If they work together, how long will it take the

lilavasa [31]

Max mows a yard in 45 minutes and Jan takes twice as long mowing the same yard. If Max and Jan both work together, it will take approximately 30 minutes to for them both to mow the yard.

It take Max 1 minute to mow 1/45 of the yard.
It takes Jan 1 minute to mow 1/90 of the yard.

1/45+1/90 =3/90 = 1/30 of the yard can be mowed by both in just one minute. This is how to get the answer, 30 minutes.
