What does -4=2p+10 equal ?

Tanya [424]

I’m pretty sure this is a 2 step equation so the answer would be 3=p

STEPS- -4=2p+10
1) subtract 10 from both sides
2) divide 2 from positive 6 because that’s what you should’ve got from two negatives
3) then 3 is equal to p

Evaluate the problem below. Please show all your work for full credit. Highlight or -4 1/2+5 2/3

Answer:

$\frac{7}{6}$

Step-by-step explanation:

$-4\frac{1}{2} + 5\frac{2}{3} =$

For the first term you have to multiply 2x(-4) and add 1, for the second term you have to multiply 3x5 and add 2.

$\frac{2(-4)+1}{2} + \frac{3(5)+2}{3} =$

$-\frac{9}{2} +\frac{17}{3} =$

Now you need to find the lowest common multiple between the denominators, just cross multiply as it is shown:

$-\frac{9}{2} (\frac{3}{3} )+\frac{17}{3} (\frac{2}{2} )=$

$-\frac{27}{6} +\frac{34}{6} = \frac{7}{6}$

finally you get the result by doing a substraction = 7/6, or 1 $\frac{1}{6}$
