Answer:

x = 3

ST = 24

Step-by-step explanation:

if T is the midpoint then ST = TU

8x = 2x + 18 move like terms to the same side

8x - 2x = 18 subtract like terms

6x = 18 divide both sides by 6

x = 3 to find ST replace x with 3

Please help me solve this, also the cut off part just says dont use spaces in your answers

Alisiya [41]

the equation of the line is

y = -3x + 6

slope is m = -3

as we know that for parallel lines, the slope is always equal.

so the slope of the new line is also m = -3

it is also passing through (-4,9)

so the equation of the line i s

$y-9=m(x-(-4))$

m= -3

$y-9=-3(x+4)_{}$

$\begin{gathered} y-9=-3x-12 \\ y=-3x-12+9 \\ y=-3x-3 \end{gathered}$

so the answer is y = -3x - 3

The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many more girls than boys are there?

lisov135 [29]

Answer:

Step-by-step explanation:

sum the parts of the ratio, 3 + 4 = 7 parts

Divide the number of students by 7 to find the value of one part of the ratio

35 ÷ 7 = 5 ← value of 1 part of the ratio, then

3 parts 3 × 5 = 15 ← number of boys

4 parts = 4 × 5 = 20 ← number of girls

20 - 15 = 5

There are 5 more girls than boys
