Answer:
1
Step-by-step explanation:
1 plus 29 equals 30
Answer: 2 and 7/12
Step-by-step explanation: To subtract 4 - 1 and 5/12, first subtract the fractions. Since 4 has no fraction, imagine the fraction 0/12.
Notice however that we can't subtract 0/12 - 5/12.
So, let's rewrite 4 and 0/12 as 3 + 1 and 0/12 or 3 + 12/12 by changing 1 and 0/12 into an improper fraction.
Now we have 3 and 12/12 - 1 and 5/12.
Now we can subtract our fractions 12/12 - 5/12 and we get 7/12. Next we subtract our whole numbers 4 - 1 to get 3.
So 5 - 1 and 5/12 is 2 and 7/12.
Answer:
36 units
Step-by-step explanation:
Split the parallelogram into 3 shapes. Two right triangles and one rectangle.
Find the length of all the sides.
Triangle one: Triangle two:
Leg 1: 8 a^2+b^2=c^2 Leg 1: 8 a^2+b^2=c^2
Leg 2: 6 8^2 + 6^2 = c^2 Leg 2: 6 8^2 + 6^2 = c^2
Hypotenuse: ? 64 + 36 = c^2 Hypotenuse: ? 64 + 36 = c^2
100=c^2 100=c^2
c=10 c=10
Hypotenuse One: 10 units
Hypotenuse Two: 10 units
Base One Length: 8 units
Base Two Length: 8 units
Add all these numbers up and your answer would be 36 units.
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 .
Answer:
When you multiply an odd number of negatives you get a negative result. When you multiply an even number of negatives you get a positive result.
First, multiply normally.
25x10x5
1100
Then determine whether the sign is positive or negative. Since there is an odd number of negatives, the sign is negative.
So, the answer is -1100.
