Answer: The radius is 4 units. (Answer B)
I: 635=dimes*10+quarters*25
or shorter
635=d*10+q*25
II: d=q*3+3
Substitute II (d=3q+3) into I to replace d:
635=d*10+q*25
635=(3q+3)*10+q*25
635=30+30q+25q
605=55q
11=q
-> 11 quarters
"What expression represents the number of dimes if q represent quarters"
insert q=11 into II:
II: d=q*3+3
d=11*3+3
d=33+3
d=36
Answer:
u=32
Step-by-step explanation:
Hey There!
Those are a pair of complementary angles we can tell because it has a square at the angle.
When angles are complementary they add up to 90
So given one angle we subtract that by 90 to find the missing angle
90-58=32
therefore u = 32
Convert percent into a decimal by moving the percent sign two places to the left.
39% => 0.39
'Of' in math means multiply.
0.39 * 50 = 19.5
