12.5² = 156.25
So yes, out of the cloth with an area of 170 cm², she can make the square handkerchief. She would also have 13.75 cm² of cloth left over.
4x + 5(3x+2) = 48
4x + 15x + 10 = 48
19x + 10 = 48
19x = 38
x = 2
y = 3x + 2
y = 3(2) + 2
y = 6 + 2
y = 8
Answer:
44 square cm
Step-by-step explanation:
Total Area = Area of triangle + Area of rectangle
= (1/2 * base * height) + (Length*Width)
= (1/2 × 8 × 6) + ( 10 × 2)
= 24 + 20
= 44 square cm
Let X = the number of hours the server works.
The equation for the amount Nick spends is 15x + 47
The next job pays 14x + 54
Set the equations to equal and solve for x:
15x + 47 = 14x +54
Subtract 14x from both sides:
X + 47 = 54
Subtract 47 from both sides:
X = 7
Now replace x with 7 in the second equation:
14x + 54 = 14(7) + 54 = 98 +54 = 152
The job would pay $152 and be 7 hours long.
