how to solve 2 - 1/2

Answer:

Step-by-step explanation:

assuming the two angles are supplementary, add them together to equal 180.

0.19x+57+0.06x+36=180

combine like terms

0.25x+93=180

subtract 93 from both sides

0.25=87

divide both sides by 0.25

x=348

CBD is 56.88 degrees

Answer: yes

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

107 minus 39 is equal to 146. 180 (total degrees for triangles) minus 146 is 34. The triangles are equal

Answer:

81 feet ²

Step-by-step explanation:

Given that:

Dimension of rectangular prism :

6 feets by 2.5 feets by 3 feets

To obtain the amount of wrapping paper required to cover the box ; we find the area of the box ;

Area of box = 2(wl + hl + hw)

Area of box = 2(6*2.5 + 6*3 + 2.5*3)

Area of box = 2(15 + 18 + 7.5)

Area of box = 81 feet²

Number of biking outfit Makayla buy is 7

Given:

Total amount spend by Makayla = $740

Cost of bicycle = $465.34

Cost of 4 bicycle reflectors = $13.25(each)

Cost of pair gloves = $18.12

Cost of each biking outfit = $25.69 each

Find:

Number of biking outfit Makayla buy

Computation:

Assume;

Number of biking outfit Makayla buy = a

Total cost = Cost of bicycle + Total Cost of 4 bicycle reflectors + Cost of pair gloves + Total cost of biking outfit

465.34 + 4(13.25) + 18.12 + a(25.69) = 740

465.34 + 53 + 18.12 + a(25.69) = 740

536.46 + a(25.69) = 740

a(25.69) = 740 - 536.46

a(25.69) = 203.54

a = 7.9229

Rounding number to less

So.

Number of biking outfit Makayla buy = 7 (Approx.)

In this triangle it is given that one angle if of 30⁰ and another one is of 90⁰

so By using ANGLE SUM PROPERTY we can solve it

so,

30⁰+ 90⁰ + 4x - 4⁰ = 180⁰(ASP)

120⁰ + 4x - 4 = 180⁰

4x - 4 = 60⁰

4x = 64

x = 16⁰

Hence solved

ill try:

18 - 7 = 11

11 - 5 = 6

Step-by-step explanation:

that was my answer

The equation has 3 solutions (determined by the degree of polynomial and non-extreme case).

If you use cubic equation to try and solve the equality you get

[tex]x_1\approx-0.88 \\ x_2\approx1.35 \\ x_3\approx2.53[/tex]

Clearly third one is in [tex](2,3)[/tex] so the statement that one solution is between 2 and 3 is true.

Answer:

90/13, 45/13

Step-by-step explanation:

[tex] - 2 = x \\ 7x + 9y = - 45 \\ \\ 7 \times ( - 2)y + 9y = - 45 \\ y = 9 \\ \\ 7x + 9 \times 9 = - 45 \\ x = - 18 \\ (x.y) = (- 18.9) \\ \\ [/tex]

Simplify:

[tex] - 2 \times 9 = - 18 \\ 7 \times ( - 18) + 9 \times 9 = - 45 \\ - 18 = - 18 \\ - 45 = - 45[/tex]

Answer:

missing angle = 41, b. 45, c. 72

Step-by-step explanation:

A circle has 360 degrees, so add all of the existing angles

48+45+129+97 = 319 and 360-319 = 41

25/200 = 12.5% so 12.5% of 360 = .125x360 = 45

Sector 129 represents 129/360 = 35.83% so 200x.3583=72 cars

Answer:

58°

Step-by-step explanation:

Start with the equation 2x + 2 + 90 = 148

( I got the 90 from Angle B since it is a right angle.)

Combine like terms 2x + 92 = 148

( 90 and 2 didn't have variables so you could add them together.)

Subtract 92 from both sides 2x + 92 = 148

                                                      -92   -92

(The opposite of addition is subtraction.)

Now write out the new equation 2x = 56

Divide both sides by 2 [tex]\frac{2x}{2}[/tex] = [tex]\frac{56}{2}[/tex]

You'll end up with... x = 28

To find the measure of angle BAC, plug in 28 where the x value is 2(28) + 2

This gives you the answer 58°

Answer:

40 + 24 = 8(5 + 3)

Step-by-step explanation:

Consider the expression 40 + 24. Find the greatest common factor of the two numbers, and rewrite the expression using distributive property

Step 1

We find the GCF

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

Then the greatest common factor is 8.

Step 2

Rewriting the expression using distributive property.

The factors of 40 and 24 that would give us the sum of 8 is given as 5 and 3

Therefore, using Distributive property

40 + 24 = 8(5 + 3)
