2/3 x + 15 = 17
2/3 x = 17 - 15
2/3 x = 2
x = 2 / (2/3)
2/1 * 3/2 = 6/2 = 3
x = 3

So
2\3x+15=17                        FIRST SUBTRACT 15 FROM BOTH SIDES!!!!
       -15=-15                      =15 AND -15 CANCEL EACH OTHER AND 17-15=2
2\3x=2                              THEN DIVIDE BOTH SIDE BY 2\3x
÷2\3x=÷2\3x                      2\3 = 0.6666667
                         2\3x and 2\3x cancel each other and 2\0.6666667 = 0.33333333
                        
Answer would be rounded to nearest tenths

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!
Mila [183]

Answer:

m\angle H = 44.4\°.

Step-by-step explanation:

Given:

In Right Angle Triangle GIH

∠ I = 90°

GI = 7    ....Side opposite to angle H

GH = 10  .... Hypotenuse

To Find:

m∠H = ?

Solution:

In Right Angle Triangle ABC ,Sine Identity,

sin \ H = \frac{Oppsite\  side\  to\  \angle H}{Hypotenuse}

Substituting the values we get;

sin\ H = \frac{7}{10} = 0.7

Now taking sin^{-1} we get;

\angle H = sin^{-1}\ 0.7 = 44.427

rounding to nearest tenth we get.

m\angle H = 44.4\°.

Hence m\angle H = 44.4\°.

Please help me!! You must be good in math.
ivolga24 [154]
It is SAS because
1) it is given that sides are equal (AB=CD)
2)it is also given that angles B and C are equal
3) BC is a common side so it is equal in both triangles.

answer: SAS

What is 20% by 37 decreased
Ghella [55]

Answer:

<u><em>37 decreased by 20% is </em></u><u><em>29.6.</em></u>

Step-by-step explanation:

<u><em>To do this, what we do is simply </em></u><u><em>take 20% of 37 and subtract it from 37.</em></u>

<u><em>20% of 37.</em></u><u><em> A trick to easily figure this out is </em></u><u><em>multipling 37 by 20 and dividing by 100.</em></u>

<u><em>37*20 = 740</em></u>

<u><em>740 / 100 = 7.40</em></u>

<u><em>37 - 7.40 = 29.6</em></u>

<u><em>37 decreased by 20% is </em></u><u><em>29.6.</em></u>

Explain how you would graph the line containing a slope of-1/5 that goes through the point (1,-4)​
madam [21]

Answer:

y= -1/5x + 1/5

Step-by-step explanation:

y- y1 = m(x - x1)

Slope m=-1/5

(1, -4)

1 = y1

-4 = x1

y- 1 = -1/5(x-(-4))

y-1 = -1/5(x+4)

y-1= -1/5(x)+ -1/5(4)

y-1 = -1/5x + -4/5

add one to both sides

y= -1/5x + -4/5 + 1

y = -1/5x + 1/5
