Answer:

The answer is 6 units.

Step-by-step explanation: Since the triangles are similar, they have a common factor between the two triangles. The side four units long on the smaller triangle corresponds to the side that is eight units long on the bigger triangle by two times. So, the side that is three units long should correspond to the side of the bigger triangle by two times, which would equal six units.

Answer:

XZ = 6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{AB}{XY} = \frac{AC}{XZ}, substituting

\frac{4}{8} = \frac{3}{XZ} ( cross- multiply )

4XZ = 24 ( divide both sides by 4 )

XZ = 6

strojnjashka [21]

Answer:

2x + y = 15

Step-by-step explanation:

Total amount with Manuel = $15

Cost of apps = $2

Cost of song = $1

x = number of apps purchased

y = number of songs purchased

Cost of apps × number of apps purchased + Cost of song × number of songs purchased = Total amount with Manuel

2*x + 1*y = 15

2x + y = 15

The linear equation that represents the combination of apps and songs manuel can purchase is 2x + y = 15

bogdanovich [222]

Answer:

76 on second exam, 80 on third exam

Step-by-step explanation:

First, find the total of all 3 test scores by multiplying the average by the number of elements. 81 · 3 = 243.

The first score is 83 so 243 - 83 = 160. 160 is the other two test scores combined.

To find the other 2 scores, divide 160 by 2, which is 80.

The second score is 4 less so it will be 76. The third score is 80.
