Solve for m. <br>5m + 3m - 8 = 64<br> a m = 9<br> b m = 2<br> c m = -2 <br>d m = 5
Vesnalui [34]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{m = 9}}}}}

Option A is the correct option

Step-by-step explanation:

\sf{5m + 3m - 8 = 64}

Collect like terms

⇒\sf{8m - 8 = 64}

Move 8 to right hand side and change it's sign

⇒\sf{8m = 64 + 8}

Add the numbers

⇒\sf{8m = 72}

Divide both sides of the equation by 8

⇒\sf{ \frac{8m}{8}  =  \frac{72}{8} }

Calculate

⇒\sf{m = 9}

Hope I helped!

Best regards!!

Answer:

$618.95 rounded up. 0.004c

£388.09 on rent and $230.84 food

We can round up and state $619 to nearest tenth.

Or leave as non rounded Total $618.93

Step-by-step explanation:

27% of 1,437.40=388.09

1,437.40 - 388.09 = 1049.31

22% of 1049.31 = 230.8482

$230,84   Shown here, as not round up or down as 230.84 as £388.09 was not rounded up from 388.098.

= $618.95 rounded up. 0.004c

In one year, Michael earned $6300 as a work study in college. He invested part of the money at 9% and the rest at 7%. If he rece
Nitella [24]
Let x represent invested money at 9% and y at 7%
Now we write system:
x+y = 6300
1.09*x + 1.07* y = 6300 + 493 = 6793

1.09x + 1.09y = 6867
Here we multiplied first equation with 1.09 and now we will subtract second from first:

0.02y = 74
y = 3700
x = 6300-3700 = 2600

Michael invested 2600 at 9% and 3700 at 7%
