Hope this helps have a good day! <3
If solving by elimination do this:
1.Add both rows together
-5x =45
2. Solve for x
x=-9
3. Substitute x into either equation (I will use y=7x+67)
y=7(-9)+67
y=4
4. Get variables
x=-9, y=4
Answer:
1- 10% of -80 is -8.
2- 28 is 4% of 700.
3- 25% of a number is equal to 1/4 or 0.25 of it.
4- 13% of a number is equal to 0.13 of it.
5- 15 is 12.5% of 120.
Step-by-step explanation:
1. 10% of ________- 8
2.28 is 4% of _________
3.25% of ________
4.13% of______
5.15 is 12.5% of _____
To determine the missing numbers in the statements, the following calculations must be performed:
1-
10 = -8
100 = X
100 x -8 / 10 = X
-800 / 10 = X
-80 = X
Therefore, 10% of -80 is -8.
two-
4 = 28
100 = X
100 x 28/4 = X
2800/4 = X
700 = X
Therefore, 28 is 4% of 700.
3-
25% of a number is equal to 1/4 or 0.25 of it.
4-
13% of a number is equal to 0.13 of it.
5-
12.5 = 15
100 = X
100 x 15 / 12.5 = X
1500 / 12.5 = X
120 = X
Therefore, 15 is 12.5% of 120.
Answer:
D. No, there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.
Step-by-step explanation:
Two figures are congruent if their vertices can be mapped into one another by appropriate rigid transformation or combination of rigid transformations. Examples of the transformation are; reflection, dilation, rotation and translation.
Comparing the two figures, it would be observed that they are not congruent. Since there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.
If you would like to know how many rows of flags will Noah have in his display, you can calculate this using the following steps:
72 flags / 6 flags = 12 rows
The correct result would be 12 rows.
