This kind of problem assumes that the two people working together work for the same amount of time.
Renee can sew a quilt in 16 hours, so she can sew 1/16 of a quilt each hour. Gerena sews a quilt in 12 hours, so she can sew 1/12 of a quilt each hour.
Use the variable t represent the time Renee and Gerena work together (measured in hours). The part of a quilt Renee sews is . the part of the quilt that Gerena sews is
Together, they sew one quilt, so
Multiply all the terms by 48 (the Least Common Multiple of 16 and 12).
hours.
Answer: OPTION C.
Step-by-step explanation:
The area of a triangle can be calculated with the following formula:
Where "b" is the base of the triangle and "h" is the height of the triangle.
You know that all the triangles that compose the large triangle are equal.
According to the information given in the exercise, the base and the height of any small triangle are:
Therefore, the area of any of them is:
Since there are 4 equal triangles, you need to multiply the area obtained by 4 in order to find the area of the large triangle. This is:
Answer:
x = 4
Step-by-step explanation:
6(+4)=48
6+24=48
6+24=48
6+24−24=48−24
6=24
6=24
6/6=24
...
Answer:
14
Step-by-step explanation:
13-2=11 then 11x 3 =33 then 33-25=8+=14
Answer:
-7 and -8
Step-by-step explanation:
Generally with this kind of problem it is helpful to construct equations representing the words.
Let's let:
Lesser integer = X
Greater integer = Y
The integers are consecutive, meaning that they are only one integer (number) apart. So,
Y = X+1
From the problem, we know that
Y = 9 + 2X
Now, we can sub in the equation from above.
(X + 1) = 9 + 2X
We now solve for X:
1 - 9 = 2X - X
-8 = X
Y = -8 + 1
Y = -7
