Answer:
16 : 100 = 8 : 50 = 4 : 25
Step-by-step explanation:
You just half each side by the same number
Answer:63
Step-by-step explanation:
63/7+25=34
Answer:
Slope=-2/3, y-intercept=2, x-intercept=3
Step-by-step explanation:
Let the independent variable be x and dependent variable be y
y=h(x)
h is a linear function so it is represented in the general form of y=mx+c where
m is slope and c is the y-intercept.
Given "the dependent variable decreases 2 units for every 3 units the independent variable increases."
When x increases by 3, y decreases by 2
So the slope = rate of change of y / rate of change of x = -2/3
Given h(0)=2, h(0)=m(0)+c=2
c=2
Combining slope and y-intercept, y=-2/3*x+2
x-intercept is when y=0
0=-2/3*x+2
2/3*x=2
x=2*3/2=3
x-intercept=3
Point-slope form
y-y₀=m.(x-x₀)
P(3,5)
m=2
y-5=2(x-3)
3 rolls of steamer + 2 packages of balloons = $10 -------------- (1)
2 rolls of steamer + 1 package of balloons = $6.25 --------- (2)
(2) x 2:
4 rolls of steamer + 2 package of balloons = $12.50 --------- (2a)
(2a) - (1):
1 roll of steamer = $2.50 ----------- Sub into (1)
3 ($2.50) + 2 packages of balloons = $10
$7.50 + 2 packages of balloons = $10
2 packages of balloons = $10 - $7.50
2 packages of balloons = $2.50
1 packages of balloons = $1.25
1 packages of balloons = $1.25
1 roll of steamer = $2.50
1 packages of balloons + 1 roll of steamer = $1.25 + $2.50 = $3.75
