Add parentheses to the equation below so that x = 90. 3 + 2^2 /4 - 10 = x
8090 [49]

Answer:

(3+2)²*4-10=x

Step-by-step explanation:

If it was a typo and is actually times 4, not divided by 4, then here is the answer:

(3+2)²*4-10=x

5²*4-10=x

25*4-10=x

100-10=x

90=x

If it actually was divided by 4, I don’t see any way it can be done.

ahrayia [7]

Answer:

The equation is in the form 268 = L + 225 and the points of left - handed shots are 43 .

Step-by-step explanation:

As given

Eloise scored a total of 268 points during the basketball season.

Of her total points, L points came from left-handed shots.

She scored 225 points with right-handed shots.

Than the equation becomes

Total points = Left handed points + Right handed points

268 = L + 225

Solving the equation

L = 268 - 225

L = 43

Therefore the equation is in the form 268 = L + 225 and the points of left - handed shots are 43 .

If the ratio of star shaped cookies to circular cookies is 5: 6 and the ratio of circular cookies to triangular cookies is 3: 10
SCORPION-xisa [38]

Answer:

1:4

Step-by-step explanation:

Without loss of generality, let there be 5 star shaped cookies. Following the proportions given, there will be 6 circular cookies. We can set up the following proportion to find out how many triangular cookies there would be:

\frac{3}{10}=\frac{6}{x},\\3x=60,\\x=20.

Therefore, for every 5 star shaped cookies there will be 20 triangular cookies.

Simplifying this ratio we have 5:20 \implies \boxed{1:4}.
