Answer:
C.) percent= 20%, Amount=unknown, Base =50
Step-by-step explanation:
The percent is the percent, so 20% is the percent.
The number you take the percent of is the base. The base is 50.
Once you calculate the percent of the base, you get the amount.
We are given the percent, 20%, the base, 50, but not the amount.
The equation in y=mx+b form is 1/4x-9.
(3 3/4) / (2/8).....turn mixed number to improper fraction
(15/4) / (2/8)...when dividing fractions, " flip " what u r dividing by, then multiply.
15/4 * 8/2 = 120/8 = 15
Given:
John had to pay a combined electric and gas bill $150.
The electric portion of the bill was $90.
To find:
The ratio of money spent on electric to that on gas.
Solution:
Let x be the amount of gas bill.
The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150. So,
The gas portion of the bill was $60.
The ratio of money spent on electric to that on gas is:
Therefore, the ratio of money spent on electric to that on gas is 3:2.
Y=3ˣ and y=2x+1
one of them is the grouth of the flies and the other is how many the iguana can eat per week (I'm thinking the y=3ˣ is the population growth)
where x=number of weeks and y=number of flies
so he should graph y=3ˣ and y=2x+1 and see the solution wich will be the inersection point of the 2 equations
to graph y=3ˣ, graph the points (0,0) and (1,3) and (2,9) and (5,243) then connect the points in a curve
to graph y=2x+1, graph the points (0,1) and (2,4) then connect the points with a straight line
where they intersect is the week and number of flies
to graph y=2x+1
