Answer:
2.5 gallons of black paint
17.5 gallons of white paint
Step-by-step explanation:
X=1 because, −2.8x+5.6<8.4
2 because it is the only number smaller than 5
Answer: x=10 and y=5
Step-by-step explanation: Let be the number of hours worked by the first mechanic.
Let be the number of hours worked by the second mechanic.
They worked for a combined total of hours. So we have the following equation.
The first mechanic charged per hour and worked for hours.
So, the first mechanic charged dollars.
The second mechanic charged per hour and worked for hours.
So, the second mechanic charged dollars.
Together they charged a total of . So we have the following equation.
The two equations above give us a system of linear equations.
We can solve the first equation for .
We then substitute for in the second equation to find .
Look at line CDF and see how it includes all 3 shapes.
The angle of the square is 90 and the equilateral triangle is 60 because 180/3
90 + 60= 150
180 - 150 = 30
Angle ADE is 30 degrees
Since it is an isosceles triangle, the base angels are the same so angle AED is also 30 degrees
You know that DEF is equal to 60 so...
60 + 30 = 90 degrees
Hope this helps and have a nice day!
