Answer:

Step-by-step explanation:
Ok, so first substitute x for 4 in
"g(x) = 5x + 1", and x for 3 in
"k(x) = 2/x + 2x". Now you got:
g(4) = 5(4) + 1
k(3) = 2/(3) + 2(3)
Now you can solve each individually.
g(4) = 5 × 4 = 20
20 + 1 = 21
g(4) = 21
k(3) = 2 × 3 = 6
6 + 2/3 = 6 2/3
k(3) = 6 2/3
g(4) + k(3) = 21 + 6 2/3 = <u>27 2/3</u>
Hope this helps :)
158.71 rounded to the nearest ten dollars would be $160.00
then to estimate 10% since 10% starts with a 1, just remove the zero from both numbers
so 160 becomes 16
the tip would be $16

Answer:
75% of the votes were in favor.
Step-by-step explanation:
To find the percent(rate), we use the formula r=p/b
The question is "What percent(rate) of 56 is 42?"
So fill in the formula and it will show as r=42/56, which is the rate will be equal to 42 divided by 56.
Perform the calculations and the result will show 0.75
Convert the decimal to a percent by moving the decimal point two places to the right and you will have 75% as your answer.
