Answer:

triangle VUT ~ trangle VLM by SAS~

Step-by-step explanation:

We have information about two pairs of sides.

We also see that that there is pair of included angles. The included angles are vertical and congruent.

We need to check the ratios of the lengths of corresponding sides.

49/14 = 3.5

28/8 = 3.5

The pairs of corresponding sides have lengths in the same ratio. There is an included pair of congruent angles.

The triangles are similar by SAS Similarity.

The sum of two numbers is 49 and the difference between these two numbers is 9. What are these two numbers?Shown working out pl

8_murik_8 [283]

Let numbers be x and y

ATQ

x+y=49---(1)

x-y=9---(2)

Adding both

$\\ \sf\longmapsto 2x=58$

$\\ \sf\longmapsto x=\dfrac{58}{2}$

$\\ \sf\longmapsto x=29$

Now putting value in eq(2)

$\\ \sf\longmapsto x-y=9$

$\\ \sf\longmapsto 29-9=y$

$\\ \sf\longmapsto y=20$

Answer:

$x^4-9x^2-28x=-12$

Step-by-step explanation:

$(x^2-4x)^2+7x^2-28x+12=0$

$(x^4-16x^2)+7x^2-28x=-12$

$x^4-9x^2-28x=-12$

Juan and Nina are in the Junior High Orchestra. As part of the orchestra they each have to learn two instruments. Juan is learni

Whitepunk [10]

Answer:

Nina practiced the viola for 11.25 hours last week.

Step-by-step explanation:

Juan practiced the violin for 9 hours last week. For each 3 hours that he practices the violin, he practices 2.5 hours of cello. So

3h violin - 2.5h cello

9h violin - xh cello

$3x = 9*2.5$

$x = 7.5$

He practiced 7.5 hours of cello, the same as Nina.

For every 3 hours Nina spends practicing the viola she practices the cello for 2 hours. So:

3h viola - 2h cello

xh viola - 7.5h cello

$2x = 3*7.5$

$x = 7.5*1.5$

$x = 11.25$

Nina practiced the viola for 11.25 hours last week.

A variable needs to be eliminated to solve the system of equations below. Choose the

notsponge [240]

Answer:

x=-2

y= 8

Step-by-step explanation:

Given data

10x – 2y = -36-----------1

7x – 2y = -30--------------2

-Subtract to eliminate y

3x-0= -6

3x= -6

x= -6/3

x= -2

Put x= -2 in

7(-2)– 2y = -30

-14-2y=-30

-14+30=2y

16=2y

y= 16/2

y= 8
