Answer:

x = 10

Step-by-step explanation:

Given

AB = 8

AC = x

QR = 12

QS = 15

Required

Find x

Because both triangles are similar, we have:

AB : AC = QR : QS --- Equivalent ratios

This gives:

8 : x = 12 : 15

Convert to fraction

\frac{8}{x} = \frac{12}{15}

Cross Multiply:

12 * x = 8* 15

12x = 120

Divide both sides by 12

x = \frac{120}{12}

x = 10

Graph the linear equation y=7x+1
Kay [80]

Answer:

See attached graph.

Step-by-step explanation:

To graph the equation, use its form y = mx+b to guide you.

Since y = 7x + 1 then m = 7 and b=1. Start on the y-axis at  1. Plot this points. From this point go up 7 units and over 1 units. Plot this point (1,8). Connect the points.

The ages of two sisters are consecutive even integers. Twice the age of the youngest exceeds the oldest by 8. How old is the you
dezoksy [38]

Answer:

10 years old

Step-by-step explanation:

Let's say the age of the younger sister is x. Then the age of the older sister must be x + 2 because the ages are consecutive <em>even</em> numbers.

"Twice the age of the youngest exceeds the oldest by 8" means that we multiply x by 2 and set that equal to (x + 2) + 8:

2x = (x + 2) + 8

2x = x + 10

x = 10

So, the youngest sister is 10 years old.
