Answer:

480 minutes

Step-by-step explanation:

We can write this relationship as y=0.11x+18 and then solve for x when y=70.80:

y=0.11x+18\\\\70.80=0.11x+18\\\\52.80=0.11x\\\\480=x

Therefore, you spent 480 minutes talking.

mihalych1998 [28]
How much bigger is B than A , so Side length B- A = (-4x+18) - (2x-7) = -6x+25
So perimeter = 4x length = 4x(-6x+25) = -24x+100 = 100-24x 
How much bigger? 100-24X

I really need help they never taught me this in my old school.
SIZIF [17.4K]
To find this, just plug the numbers into the expressions.

5x = y
5(2) = 7
10 = 7
So it can't be A.

x + 2 = y
2 + 2 = 7
4 = 7

x + 4 = y
2 + 4 = 7
6 = 7

2x + 3 = y
2(2) + 3 = 7
7 = 7

The correct answer is
D. 2x + 3

The diagram below represents which percent?
nirvana33 [79]

Answer:

80%

Step-by-step explanation:

There are 4 shaded sections and 1 unshaded section, so five sections in total.

4 sections are shaded, so the fraction would be 4/5.

Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).
