Answer:

Step-by-step explanation:

⇔ We can set up an equation using the information given to us

$16 =1 \frac{2}{10} x+-8$

We can that 16 is equal or the same as, one and two tenths times a number which is 'x' added to negative 8

⇔ The minus cancels out the plus

$16=1\frac{2}{10} x-8$

⇔ Add 8 to both sides to isolate $1\frac{2}{10} x$

$24 =1 \frac{2}{10} x\\$

⇔ Convert $1\frac{2}{10} x$ to improper fraction to make solving easier

$24 = \frac{12}{10} x$

⇔ Multiply both sides by 10 to isolate 12x

240 = 12x

⇔ Divide both sides by 12 to isolate x

20 = x

→ The 'number' is 20

Answer:

Answer is 5x+2

Step-by-step explanation:

$Given \: f(x) = 4x - 1 \: \: and \: \\ g(x) = x + 3 \\ f(x) + g(x) = 4x -1 + x + 3 \\ = 5x + 2$

HAVE A NICE DAY!

ivann1987 [24]

Answer:

x = -7

Step-by-step explanation:

−30=5(x+1)

Divide each side by 5

-30/5=5/5(x+1)

-6 =x+1

Subtract 1 from each side

-6-1 = x+1-1

-7 =x

Triangle R Q S is cut by line segment T U. Line segment T U goes from side Q R to side Q S. The length of Q T is 32, the length

Marizza181 [45]

The statement that is true is option A that is Line segment TU is parallel to line segment RS because StartFraction 32 Over 36 EndFraction = StartFraction 40 Over 45 EndFraction.

<h3>What is the line segment about?</h3>

The law of the side- splitter connote that when f the line is parallel to a side of the triangle and if that said line do intersects the other 2 sides, tt is said to divides those given sides proportionally.

So the converse means that when the sides are proportional so therefore, the side TU is said to be parallel to the side RS.

Thus;

$\frac{QT}{TR}$ = $\frac{32}{36} = \frac{8}{9}\\\\ \\$

$\\\frac{QU}{US} =\frac{40}{45} = \frac{8}{9}\\$

Therefore, the ratios are equal and as such TU is parallel to RS

Hence, The statement that is true is option A that is Line segment TU is parallel to line segment RS because StartFraction 32 Over 36 EndFraction = StartFraction 40 Over 45 EndFraction.
