In which question is r = -17 a solution?

devlian [24]

Answer:

None

Step-by-step explanation:

Simply solve each linear equation and get value of R.

Or another way can be to put value of R in all four options and find whether left hand side is equal to right hand side or not.

A) $3-\frac{2R}{4}=10$

$-\frac{R}{2}=7$

R = -14

B) $\frac{3}{4}-2R =10$

$-2R=10-\frac{3}{4}$

R = -37/8

C) $3(R-4)=10$

$R-4=\frac{10}{3}$

$R=4+\frac{10}{3}$

R = 22/3

D) $3-\frac{R}{4}=10$

R = -28

So, none of the option's are having solution R =-17.

Lila evaluates the expression using the following steps:(−7.13+63.97)+(−54.8−3.4)−71.1+(−58.2)−129.3Describe the error that Lila

mihalych1998 [28]

Lila's error was that she added -7.13 to 63.97 to get -71.1

Lila steps are as folows

(−7.13 + 63.97) + (−54.8 − 3.4) = −71.1 + (−58.2) = −129.3

In the first bracket, Lila was suppose to subtract 7.31 from 63.97 since there is a negative in front of 7.31.

So, the correct expression should be

(−7.13 + 63.97) + (−54.8 − 3.4) = 56.84 + (−58.2) = 56.84 - 58.2 = −1.36

So, Lila's error was that she added -7.13 to 63.97 to get -71.1
