A man is 25 years old. His mother is exactly three times his age. How old will the man’s mother be when he is 35 years old?

klio [65]

Answer:

Step-by-step explanation:

Note the mother is 3x his age when he is 25 years old. Multiply 3 with 25:

3 x 25 = 75

Ten years pass (35 - 25 = 10). Add 10 to 75:

75 + 10 = 85

When the man is 35 years old, his mother will be 85 years old.

100 POINTS! PLEASE HELP!

Semmy [17]

Apply angle bisector theorem

$\\ \sf\longmapsto \dfrac{9}{15}=\dfrac{3}{5}=\dfrac{2x-1}{3x}$

$\\ \sf\longmapsto 9x=5(2x-1)$

$\\ \sf\longmapsto 9x=10x-5$

$\\ \sf\longmapsto 10x-9x=5$

$\\ \sf\longmapsto x=5$

$\\ \sf\longmapsto \dfrac{4}{3}=\dfrac{x}{2.25}$

$\\ \sf\longmapsto 4(2.25)=3x$

$\\ \sf\longmapsto 3x=9$

$\\ \sf\longmapsto x=3$

Hope it helps

Y varies directly with x. When x is 4 y is 8. Find y when x = 10.

grandymaker [24]

Step-by-step explanation:

y = 4 when x = 8 So, 4 = 8k

k = 1/2

y = (1/2)x

Therefore, when x = 10, y = (1/2)(10) = 5

Given:

Fynjy0 [20]

Answer:

Option B is correct.

$\triangle RST \cong \triangle TUR$

Step-by-step explanation:

Given: RSTU is a parallelogram.

By definition of parallelogram, two pairs of opposite sides are congruent in length.

⇒ $TU \cong RS$ and $TS \cong RU$

In triangle RST and triangle TUR

$RS \cong TU$ [Side]

$TS \cong RU$ [Side]

$RT \cong RT$ [Common side]

SSS(Side-Side-Side) postulates states that if three sides of one triangle are congruent to three sides of other triangle, then the triangles are congruent.

then, by SSS postulates we have;

$\triangle RST \cong \triangle TUR$
