7x^2 - 3x + 7

Step-by-step explanation:

5x^2+3x+4+2x^2-6x+3

7x^2-3x+7

Answer: D

Explanation: You add 5x2 and 2x2 giving 7x2. You then add 3x and 6x but because there is 2x2-6x you actually would just leave it as is (In this instance). Then add 4 and 3 giving you 7. Therefore, The answer is 7x2-3x+7

Answer:

x = 6

Step-by-step explanation:

8x + 2 + 70 + 60 = 180

8x + 132 = 180

8x = 48

x = 6

Answer:

6

Step-by-step explanation:

multiple 30× .20% which equals 6. Then you will add 30 +6=36. So, Lane will do a total of 36 push-ups everyday

Answer:

Step-by-step explanation:

either 1 foot or 33 ;-;

The value 5.1 feet long is a string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

A string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.

Let the value is C.

The Pythagoras' theorem,

C² = (11)² + (12)²

C² = 121 + 144

C² = 265

C = 5.1 feet.

Therefore, the value is 5.1 feet.

Answer:

This quadrilateral is a SQUARE.

When we plot these points, we realize that they are equal distance apart.

So, when a quadrilateral has sides that are equal distance apart, that quadrilateral is a square.

The computation of the amount that should be needed today is given below:

Given that

NPER = 5

RATE  = 12%

PMT = $5,000

FV = $0

The formula is shown below:

=-PV(RATE,NPER,PMT,FV)

AFter applying the above formula, the present value is $18,025

Answer:

I believe the answer is triangle A.

Step-by-step explanation:

Since we know that sine is opposite over hypotenuse, and that the sine is being taken from angle A, triangle A is the correct answer.

Answer:

89.6 meters

Step-by-step explanation:

we have to take the square root of 501.76 to find the measure of 1 side which is 22.4 which we then multiply by 4 because a square has 4 sides.

Answer:

∠A = 175∘

Step-by-step explanation:

∠A = ∠B

5x-5= 4x+29

x = 34

∠A= 34*5+5

∠A=170+5=175

5x+5= 4x + 29

-5        

5x=4x+24

-4x -4x

x=24

m∠A=5x+5

m∠A=5(24)+5

A percentage is essentially a fraction, but lazily written. Think of a percent as 25/100, or 0.25.

Now multiply the two.

0.25x5/8.

We need to convert 5/8 to a decimal, which is 0.625.

0.25x0.625=0.15625.

Now convert the decimal to a fraction, which is 5/32.

Answer:

0.01086956521

Step-by-step explanation:

1.4 / 128.8 = 0.01086956521

Answer:

Step-by-step explanation:

m∠R = 180° - 110° [Linear pair of angles are supplementary]

m∠R = 70°

m∠S = 45° [Vertically opposite angles]

By triangle sum theorem,

m∠P + m∠R + m∠S = 180°

m∠P + 70° + 45° = 180°

m∠P = 180 -115

        = 65°

Therefore, m∠A = m∠P = 65° [Vertically opposite angles]

By triangle sum theorem,

m∠B + m∠S + m∠T = 180°

m∠B + 45° + 65° = 180°

[m∠T = 65°. Since, ∠P and ∠T are corresponding angles]

m∠B = 180° - 110° = 70°

m∠C + m∠B = 180° [Linear pair of angles are supplementary]

m∠C = 180° - 70° = 110°

m∠D + m∠T = 180° [Linear pair of angles are supplementary]

m∠D + 65° = 180°

m∠D = 115°

Answer:

D. 39

Step-by-step explanation:

BC^2 = BA^2 + AC^2

BC^2 = 15^2 + 36^2

BC = square root (1521)

BC = 39

Answer:

D) 39

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean thm formula

Formula: a² + b² = c²

15² + 36² = c²

225 + 1296 = c²

1521 = c²

[tex]\sqrt{1521} =\sqrt{c^2}[/tex]

c = 39

Step-by-step explanation:

have a great day :)

It is C

In problem C X is still being multiplied by the other variable y, and also it is still multiplying the 7 too, The other questions do not factor in the multiplication required meaning that the only answer that could be applied would be C.

Hope this helps and have a nice day.

Answer:

Step-by-step explanation:

Angles formed when we turn clockwise in the given directions,

a) N to E → 90°

b). W to NE → (90° + 45°) = 135°

c). SE to NW → 180°

d). NE to N → 360° - 45° = 315°

e). W to NE → 90° + 45° = 135°

f). S to SW → 45°

g). S to SE → 360° - 45° = 315°

h). SE to SW → 180°

i). E to SW → 90° + 45° = 135°

Answer:

56/19

Step-by-step explanation:

I'll approach this using Substitution. Since 3X = 2Y, we know that 1.5X = 1Y. We can plug that into the first equation, which gives us...

2X + 5(1.5X) = 8

2X + 7.5X = 8

9.5X = 8

19X = 16

X = 16/19

While this is not 'pretty', it does match up with how most of the answers are written (four of the answers involve "nineteenths"). With this value of X, we can solve for Y...

3X = 2Y

3(16/19) = 2Y

48/19 = 2Y

24/19 = Y

With the value of X and the value of Y, we can answer the question that's asked:

2X + Y = ?

2(16/19) + 24/19 =

32/19 + 24/19 =

56/19

Final Answer: 56/19

Answer:

[tex]x = - 1[/tex]

[tex]y = - 2[/tex]

Step-by-step explanation:

[tex]3x + 2y = - 7[/tex]

[tex]2x - 5y = 8[/tex]

Apply elimination method. Let multiply the bottom equation by -3/2.

[tex]2 \times - \frac{3}{2} x = - 3[/tex]

[tex] - 5 \times - \frac{3}{2} = 7.5[/tex]

[tex]8 \times - \frac{3}{2} = - 12[/tex]

Substitute new equation and add it to the top equation

[tex]3x + 2y = - 7[/tex]

[tex] - 3x + 7.5y = - 12[/tex]

[tex]9.5y = - 19[/tex]

[tex]y = - 2[/tex]

Now plug -2 for y into any equation and solve for x.

[tex]3x + 2( - 2) = - 7[/tex]

[tex]3x - 4 = - 7[/tex]

[tex]3x = - 3[/tex]

[tex]x = - 1[/tex]
