The answer of 799/4 is equal 1
Answer:
15
Step-by-step explanation:
1 dime = 10
1 quarter=25
x=number of coins - dimes
y= number of coins - quarters
x (10)+y(25)=10.25
x+y=50
x= 50-y
x(10)+y(25)=1025
(50-y)(10)+25y =1025
500-10y+25y=1025
500+15y=1025
15y= 1025 - 500
15y=525
y=525/15
y=35
x= 50-35=15
Answer:
see explanation
Step-by-step explanation:
Since AC = BC then ΔABC is isosceles with base angles
∠BAC =∠ABC, thus
3x + x = 70
4x = 70 ( divide both sides by 4 )
x = 17.5
----------------------------------------------------
∠ADC is an external angle of ΔABD and the external angle is equal to the 2 opposite interior angles, hence
y = 70 + x = 70 + 17.5 = 87.5
Answer:
x = 10
Step-by-step explanation:
Rearrange terms
2(5+1)−3=72
Distribute
10+2−3=72
Combine like terms
7+2=72
Subtract 2 from both sides of the equation
7+2−2=72−2
Simplify
7=70
Divide both sides of the equation by the same term
7/7=70/7
Simplify
= 10
if you could give brainliest that would be awesome! :))
