Answer:
100
Step-by-step explanation:
85 +80+100+85+x(the unknown),/the number of numbers ie 5
350+x/5=90
350+x=90 * 5
350+x=450
x=450-350
x=100
The slope of the line is 1/2.
Add '4y' to both sides of the equation, then subtract '10' both sides.
then you get 4y = 2x - 10
divide the equation by 4
you get: y = 1/2 x - 2.5
the equation for a straight line is y = mx + c where m is the slope
(4x+3) (2x+5)
we can write it,8x^2+20x+6x+15 then final result is 8x^2+26x+15
Answer:
Option A, b + 5
Step-by-step explanation:
<u>Step 1: Determine the equation to find the amount of boys</u>
b + (b + 5) = 27
b: represents boys
b + 5: represents girls where they equal 5 more than boys
Answer: Option A, b + 5
Answer: .03x + .06y ≤ 20
<u>Step-by-step explanation:</u>
Let x represent the number of minutes to the US and
let y represent the number of minutes to Brazil
and make sure their sum is not greater than $20
.03x + .06y ≤ 20
