- 38z, because -10z - 28z = 38, but you have to change into addition and that will be equal -38z.

17X+1 +20x-14 = 90 find x

professor190 [17]

Answer:

x = 2.8

Step-by-step explanation:

17x+1+20x-14 = 90

Combine like terms.

37x-13 = 90

Add 13 on both sides.

37x-13 = 90

+13 +13

37x = 103

Divide both sides by 37.

37x = 103

/37 /37

x = 2.8

(I rounded up, but if you need a more specific number, just search up 103 divided by 37.)

Hopefully this helps you!! Have an amazing day c:

$\frac{ \frac{8}{5} + ( - \frac{5}{6}) }{ \frac{1}{6} } \\ = \frac{ \frac{8}{5} - \frac{5}{6} }{ \frac{1}{6} } \\ = \frac{ \frac{48- 25}{30} }{ \frac{1}{6} } \\ = \frac{ \frac{23}{30} }{ \frac{1}{6} } \\ = \frac{23}{30} \times 6 \\ = \frac{23}{5}$

N.6 Properties of parallelograms

PolarNik [594]

Answer:

J=63

Step-by-step explanation:

3b+27=2b+57

subtract 27 from both sides

3b=2b+30

subtract 2b from both sides

b=30

K+J=180

substitute the value of b into K

2(30)+57+J=180

117+J=180

subtract 117 from both sides

J=63
