Answer: 16 hours
Step-by-step explanation:
Given
Carla earns for each hour she works
Last week she earned $148 total including tip
So, the sum of hourly income and must be equal to the total money earned
Suppose she works for hours
Thus, she works 16 hours last week
56 students represents 100 % and
X boys represent 34%,
so x= 56•34/100= 19.04 so approximately 19 boys
56-19= 37 girls signed up.
Now 37 girls represent 100% and 31 girls represent x % ,
So x= 31•100/37= 83.78% about 84% of the girls attended
A triangle is 180°, so the 3 angles should add up to 180°.
To find m∠R, you can do this:
m∠S + m∠R + m∠T = 180°
56° + m∠R + 30° = 180°
m∠R + 86° = 180° Subtract 56 and 30 on both sides
m∠R = 94°
Answer:
-2
Step-by-step explanation:
Equate the expressions for y. This gives ...
... x - 1 = 2x + 1
Add -1-x to get ...
... -2 = x . . . . your value of x
