Answer:
60
Step-by-step explanation:
Substitute 50 for y in the formula
5x+10y=800
5x+10*50=800
5x+500=800
5x=800-500
5x=300
x=300/5
x=60
Answer:
I dont know
Step-by-step explanation:
<span>First, you have to define your x and y axes, what is 0º and what direction do you turn to face 90º.... In algebra, the 0º is the angle from the x-axis, and you turn counter clockwise to get to 90º (the y-axis)
but if you use the compass directions, 0º (north) is the y axis, and you turn CLOCKWISE 90º to get to the x-axis (east)</span>
Answer:
Step-by-step explanation:
(find the percent by multiplying the percentage, .45, by the total number of shoes = 18 shoes)
% = 45%
p = 18
w = 40
(i did 100/40 which equals to 2.5 then multiplied 2.5 by the numerator so the numerator and denominator would both be equivelant.)
18/40 = 45/100
(multiply the whole (40) by the decimal value (.45) which is equal to 18)
40 x .45 = 18
(answer)
If Ms. M has 40 pairs of shoes, 18 of those shoes are sneakers.
