Stefan requires 6 hours to wash the cars by himself. In one hour he washes 1/6 of the cars. Misha can wash the cars by herself in 5 hours. In 1 hour she can wash 1/5 of the cars.
Stefan has 2.5 hours to wash the cars as he has to go to the football game. In 2.5 hours he has washed (1/6)*2.5 = 5/12 of the cars. This leaves 1 - 5/12 = 7/12 of the cars for Misha to wash. As she washes cars at the rate of 1/5 per hour, it would take her (7/12)/ (1/5) = (5*7)/12 = 35/12 hours to wash the remaining cars.
35/12 hours is equal to 175 minutes or 2 hours 55 minutes.
Misha finishes washing the cars in 2 hours and 55 minutes after Stefan leaves.
Answer:
a) <EGA and <AGB
b) <FGE and <CGB
c) <FGE and <EGC
d) <FGE and <FGA
e) <CGD=55
Step-by-step explanation:
a) Supplementary angles add up to 180 degrees.
<EGA and <AGB are supplementary.
b) Vertical angles are also called X-angles. Think of them as angles in the vertically opposite corners of the letter X.
<FGE and <CGB are a pair of vertical angles
c) Adjacent angles are next to each other.
<FGE and <EGC are a pair of adjacent angles
d) Complementary angles add up to 90 degrees.
<FGE and <FGA are a pair of complementary angles
e) <CGD=<FGA because they are vertical angles.
But <EGA=90-35=55
Therefore <CGD=55
Answer:
75.00 = price for 1 shirt
Step-by-step explanation:
-25+4y=35
*Subtract 35*
-25+4y-35=0
*add 25 (to cancel out)*
4y-35=25
*add 35 (to cancel out)*
4y=60
*Divide by 4 to get y on its own*
y=15
Hope this helps :)
