Answer:

5 & 8

Step-by-step explanation:

x-y = 3 -> x = 3+y

x+y = 13 = 3+y+y -> 3+2*y = 13

2*y = 10 -> y = 5

-> x = 3+y = 8

Ipatiy [6.2K]

Answer:

<h2>96 and 48</h2>

The circle graph shows the percentage of time Jacob spent on homework in each subject last week.Time Spent on Homework12.5%25%ar
Goshia [24]

We are given a circle graph that shows the time spent on homework last week.

Jacob spent a total of 16 hours doing homework.

The time spent on doing science homework is given by

\begin{gathered} t_{\text{science}}=25\%\: of\: 16 \\ t_{\text{science}}=\frac{25}{100}\: \times\: 16=4\: \text{hours} \end{gathered}

The time spent on doing band practice is given by

\begin{gathered} t_{\text{band}}=12.5\%\: of\: 16 \\ t_{\text{science}}=\frac{12.5}{100}\: \times\: 16=2\: \text{hours} \end{gathered}

The difference between the time spent on science homework and band practice is

difference=t_{\text{science}}-t_{\text{band}}=4-2=2\: \text{hours}

Therefore, Jacob spent 2 more hours on science homework than band practice.

10.03 is what percent of 29.5
Maru [420]
Percent formula : is/of = %/100

is = 10.03
of = 29.5
percent = x

now we sub
10.03/29.5 = x/100
this is a proportion, so we must cross multiply
(29.5)(x) = (10.03)(100)
29.5x = 1003
x = 1003/29.5
x = 34 <==== 10.03 is 34% of 29.5
