78 (1 + 2 + 3 . . + 12) so 78/3 = 26 and 11 + 12 + 1 + 2
10 + 9 + 3 + 4
8 + 7 + 6 + 5
that means you will draw one line below the 11 and across to below the 2 and the second line would be above the 8 and across to below the 4.
Seeing is believing . . .draw and label a clock face then add the two lines!
Answer:
A worked 20 hours and B worked 15 hours.
Step-by-step explanation:
Given:
Mechanic A hourly rate = $55
Mechanic B hourly rate = $45
Total charged = $1775
Let's assume Mechanic A worked 'A' amount of hours and Mechanic B worked 'B' amount of hours, then
Step 1:
First equation: A + B = 35
Second equation: 55xA + 45xB = 1775
Step 2:
First equation can be written as: A = 35 - B
Step 3: Replace value of A in second equation
Second equation: 55x(35-B) + 45B = 1775
: 1925 - 55B + 45B = 1775
: (1925 - 1775 )/10 = B
: B = 15 hours
A worked = 35 - 15
= 20 hours
Answer:
D = 90°
Step-by-step explanation:
the square on the angle means its a right angle and right angle is always 90°
Answer:
there is no solution
Step-by-step explanation:
1st switch sides: -x2+2x+1=0
2nd add similar elements: -2x + 2x = 0
1 = 0
Thus, this equation has no solution
