Answer:
4c + 6a < = 120 ...4(20) + 6(6) = 116 <== correct
Step-by-step explanation:
Answer:
We can write proportion as:

Step-by-step explanation:
A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours
Proportion:
A proportion is used when two ratios are equal. It can be written as a/b=c/d
In our case we have:
a= 30 miles
b = 1.5 hours
c = x miles
d = 4 hours
We can write proportion as:

Answer:
64 degrees
Step-by-step explanation:
Since the triangles are similar they have the same angle measures

∠P = ∠S ∠R =∠U ∠Q=∠T
We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U
In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula



subtract 116 from both sides

Therefore ∠Q is equal to 64 degrees
This is the concept of algebra, the percentage of Milk in the 4 cup mixture will be found as follows;
the ratio of milk to mixture after 1 cup was added to 3-cups was:
1/3
the total ratio of milk in the mixture was:
1/3+3/5
=14/15
thus the percentage of milk will be:
14/15*100
=93 1/3%
5-3=2, -5-1=-4, tye distance between them is -4/2 or 6 spaces
