4x + 8 - 9x = -17 what is x\


and the x has to be the same for each

Answer:

[tex]\Huge\boxed{D}[/tex]

Step-by-step explanation:

Hello There!

To find the answer we want to find the trigonometric ratio for each answer choice

important note;

[tex]sin =\frac{opposite}{hypotenuse} \\\\cos=\frac{adjacent}{hypotenuse} \\\\tan=\frac{opposite}{adjacent}[/tex]

for A,

the opposite of angle X is  12 and the adjacent of angle x is 5

so [tex]tanX=\frac{12}{5}[/tex] therefore A is not the answer

for B,

the adjacent of angle x is 5 and the hypotenuse is 13

so [tex]cosX=\frac{5}{13}[/tex] therefore B is not the answer

for C,

the opposite of angle W is 5 and the adjacent of angle W is 12

so [tex]tanW=\frac{5}{12}[/tex] therefore C is not your answer

for D,

the adjacent of angle W is 12 and the hypotenuse is 13

so [tex]cosW=\frac{12}{13}[/tex] therefore D is your answer

Answer:

86 inches

Step-by-step explanation:

16+16+27+27=

Answer:

the perimeter equals 86 ft

Step-by-step explanation:

perimeter = l + w + l + w or 2(l + w)

2(27 + 16)

27 + 16 = 43

43 * 2 = 86

Answer:

1 is 90

2 is 52

Step-by-step explanation:

1 is a right angle so its 90

for 2 angles in a triangle equal to 180

so 180-90-38 is equal to 52

(2x - 7) + ( x + 4) = 90°

2x + x - 7 + 4 = 90°

3x - 3 = 90°

3x = 90 + 3

3x = 93

x = 93/3

x = 31°

▪2x - 7

= (2 . 31) - 7

= 62 - 7

= 55°

▪x + 4

= 31 + 4

= 35°

Answer:

100

Step-by-step explanation:

1/10(3n+50)=35

3n+50=35*10

3n+50=350

3n=350-50

3n=300

n=300/3

n=100

Answer:

1st most = 8.43 inches

2nd most = 5,426 Seconds

3rd most = 1580 meters

4th most = 1500 grams

Step-by-step explanation:

8.43 inches = 0.7025 feet is most precise as it rounded to 0.7 feet it wouldn't be precise enough.

5,426 Seconds =  01:30:26. hrs mins sec can be converted.

1580 meters = 1.58 km = 158000cm  hasn't been properly converted as zeros get lost.

1500 grams = 1.5kg hasn't been precisely converted as zeros get lost.

The answer choice that has the statement that is true about the number line can be seen in the first option.

A number line is a pictorial representation of lines on a calibrated straight line that serves as a basis for expressing real numbers on a straight line.

We should equally note that:

From the given figures;

Answer:

River C. is 3,085 miles long.

River D. is 2,485 miles long.

Step-by-step explanation:

1. Divide 5,570 by 2. Your answer will be 2,785.

2. Add 300 to 1 of your 2,785, and subtract 300 from the other.

3. You will have 3,085 and 2,485. If you add them together, you will have 5,570. This confirms that these two numbers are your answers.

4. You have your answer!

Answer:

30189.155

Step-by-step explanation:

Recall the compound interest formula :

A = P(1 + r/n)^nt

P = principal = 10000

r = rate = 3.7% = 0.037

n = quarterly = 4

t = 30

A = 10000(1 + 0.037/4)^30*4

A = 10000(1 + 0.00925) ^120

A = 10000(1.00925)^120

A = 10000 * 3.0189155

A = 30189.155

Answer:

B

Step-by-step explanation:

RQ=TV

QS=VU

RS=TU

While proving that 2 triangles are congruent you have to consider the same side for both triangles.

The mistake you made was that you presumed that since both have equal sides they are equal,

In a sense that is true but you have align it in the correct way, in option D) it shows RQ is equal to TU which is wrong, RQ is equal to VT, you have align it in a proper way.

B) ΔRQS ≅ ΔTVU here it is align perfectly to be matched
