It would be 40•.25=10 which means 40-10=30 so it’d be .25 and you’d move the decimal over 2 spots so it’d be 25% off

Can you give me equation where x=16
Mashcka [7]
x = 16 in the following equations:
8 × 2 = x
8 + 8 = x
4 × 4 = x

In the following equations, x = 16:
2x = 32
<em>32 ÷ 2 = x = 16
</em>x + 5 = 21
<em>21 - 5 = x = 16</em>

An animal shelter spends $3.00 per day to care for each cat and $6.50 per day to care for each dog. Amelia noticed that the shel
Ede4ka [16]

Answer:

There were 15 cats at the shelter on Friday.

Step-by-step explanation:

Cost of caring each cat = $3.00

Cost for caring each dog = $6.50

Total money spent by shelter = $84.00

Total Cats and Dogs in the shelter = 21

Let the number of cats in the shelter = k

So, the number of dogs in shelter =  21 -k

Also according to the question:

Total expenditure on cats + total expenditure on dogs = $84.00

or, k ($3.00) + (21-k)($6.50)  = $84.00

or, 3k + 136.5 - 6.5 k = 84

or, -3.5 k = 84 - 136.5 = -52.5

⇒3.5 k = 52.5  or k = 52.5/3.5 = 15

⇒  k = 15

Hence, the number of cats in the shelter was 15 on Friday.

The formula for the distance, d, an accelerating car can travel is d = 5.6t square. how many minutes, t, doe the car take to tra
Likurg_2 [28]
Your distance(d) is 1,814.4
1814.4 m = 5.6t square
then you square root 5.6t
\sqrt{1814.4} = \sqrt{ {5.6t}^{2} }
the square root eliminates the square
\sqrt{1814.4} = 5.6t
you square root 1,814.4 m
42.6 = 5.6t
(I rounded 42.6) then divide 42.6 by 5.6
7.6 = t
(I rounded 7.6)
