Answer:

46

Step-by-step explanation:

180-70=110

now we can take a guess on the other two. What two numbers added up make 110 and are 18 apart? 46 and 64 have 4 and 6. That makes 10. So now I know that the first and second angles are 46 and 64. According to the question, the first angle is smaller. So the first angle is 46.

Answer:

first angle = 46 and the second angle = 64

Step-by-step explanation:

(x,x-18,70)

x+x-18+70=180

2x+52=180

2x=180-52

2x=128

x=64

(x+x-18+70) since x is 64 replace;

x=64

x-18= 64-18= 46

Answer:

The first box (upper left corner)

Step-by-step explanation:

Since the y-intercept is 1/4 (you can find this where x = 0), in slope intercept the second number must equal the y-intercept.

Example:

y = 3x + 2 (0,2) is the y-intercept.

Therefore, the second number must equal 1/4 which the first box is correct.

(Negative 1/4 multiplied by -1 equals positive 1/4)

Answer:

I know the first one is 6, since there's 6 sides

The second one should be Plane BDHF, since those two are exactly the same

Don't know the third one

The fourth should be segments AC, EG, and FH since they're all the same

Answer:

it is a, b, and c, but not d

Hello!

To solve this, you need to distribute and combine like terms.

Like terms are equivalent types of numbers for example;

2x and 3x are like terms, so if the equation said 2x - 5 + 3x, you would only combine 2x and 3x.

If the equation said 5 + 9 - x, you add the like terms, 5 + 9, and the simplification would be 14 - x.

Distribution is when you multiply the number outside the parenthesis into the parenthesis. for example, if an equation says, 5(x-2) = y, you would multiply 5 on the numbers x and -2, resulting in the equation, 5x - 10 = y.

--------Now lets work on your math problem.

Step 1, right the equation, 7(-9a-3)-2a7(−9a−3)−2a

Step 2: distribute numbers (remember multiplying)

7(-9a-3)-2a7(−9a−3)−2a

For the first distribution, 7(-9a-3)-2a7(−9a−3)−2a

you multiply 7 to the numbers in the parenthesis,

resulting in,

-63a - 21

Second distribution is, 7(-9a-3)-2a + 7(−9a−3)−2a

in which you multiply -7 into the numbers in the parenthesis resulting in;

-63a - 21

(did you type the equation twice if so, there are now two problems i need to solve.)

now add like terms -2a + -2a = -4a

-63a - 21 + -63a - 21 = -126a - 42

-126a - 4a - 42

Answer is -130a - 42.

If your equation was actually this, : 7(-9a-3)-2a

Then the answer would have been, -65a - 21

The line AB is not a perpendicular bisector of CD.

Perpendicular bisectors are lines that divides another line into two equal parts.

From the diagram, we can see that line CD cuts AB at the centre. Hence we can say that CD is a perpendicular bisector of AB.

The same is not applicable to line AB passing through CD. The line AB did not bisect (divide equally) line CD.

Hence we can conclude that line AB is not a perpendicular bisector of CD.

Answer:

  15 ft below the top of the water

Step-by-step explanation:

We can let distances "below the top of the water" be represented by negative numbers. Then the initial height of Jesse's hook was -12 ft. Adding line allowed his hook to sink further:

  -12 +(-3) = -15

The depth of Jesse's hook now is 15 feet below the water surface.

1. 99 = 33x + 3(3x + 5)

⇒99 = 33x + 9x + 15

⇒99 = 42x + 15

⇒99 - 15 = 42x

⇒84 = 42x

⇒42x = 84

⇒x = 84/42

⇒x = 2

2. 12z - (4z + 6) = 82

⇒12z - 4z - 6 = 82

⇒8z - 6 = 82

⇒8z = 82 + 6

⇒8z = 88

⇒ z = 88/8

⇒ z = 11

3. 2x + 3x = 62

⇒5x = 62

⇒ x = 62/5 or x = 12.4

4. 4n + 5 = 6n + 7

⇒4n - 6n = 7 - 5

⇒-2n = 2

⇒ n = -2/2

⇒ n = -1

5. 23m - 5 = 21m + 5

⇒23m - 21m = 5 + 5

⇒2m = 10

⇒ m = 10/2

⇒ m = 5

⇒3p + 4p = 13 + 8

⇒7p = 21

⇒ p = 21/7

⇒ p = 3

7. 17x - 3 + 17x + 8 = 175

⇒17x + 17x - 3 + 8 = 175

⇒34x + 5 = 175

⇒34x = 175 - 5

⇒34x = 170

⇒ x = 170/34

⇒ x = 5

8. ƒ + 41 + ƒ + 78 = 95

⇒ƒ + ƒ + 41 + 78 = 95

⇒2ƒ + 119 = 95

⇒2ƒ = 95 - 119

⇒2ƒ = -24

⇒ ƒ = -24/2

⇒ ƒ = -12

9. 3x + 18 + 93 = 180

⇒3x + 111 = 180

⇒3x = 180 - 111

⇒3x = 69

⇒ x = 69/3

⇒ x = 23

10. 6x + 2 + 40 = 90

⇒6x + 42 = 90

⇒6x = 90 - 42

⇒6x = 48

⇒ k = -14/2

⇒ k = -7

12. 3w - 6 + 8w + 4 + 50 = 180

⇒11w + 48 = 180

⇒11w = 180 - 48

⇒11w = 132

⇒ w = 132/11

⇒ w = 12

Answer:

h = 5

Step-by-step explanation:

area = 1/2 base × hight

base = 3 +h

hight =9 + 6 = 15

60 = 1/2 × 15 × (3+h)

120/15 = 3 + h

8 = 3 + h

h = 5

Answer:

h = 5

Step-by-step explanation:

The value of h can be obtained by using area of triangle formula as well as distance formula.

[tex]A(\triangle ABC) =\frac{1}{2} \times AB\times AC \\ \\ 60 = \frac{1}{2} \times \sqrt{ {( - 3 + 3)}^{2} + (9 + 6) ^{2} } \\ \times \sqrt{ {(h + 3)}^{2} + {(9 - 9)}^{2} } \\ \\ 60 \times 2= \sqrt{ {( - 0)}^{2} + (15) ^{2} } \\ \times \sqrt{ {(h + 3)}^{2} + {(0)}^{2} } \\ \\ 120= \sqrt{ 0 + (15) ^{2} } \times \sqrt{ {(h + 3)}^{2} + 0 } \\ \\ 120= \sqrt{ (15) ^{2} } \times \sqrt{ {(h + 3)}^{2} } \\ \\ 120 = 15(h + 3) \\ \\ \frac{120}{15} = h + 3 \\ \\ 8 = h + 3 \\ \\ h = 8 - 3 \\ \\ h = 5[/tex]

 Mid point of a segment divides the segment in two equal parts.

Value of x is 3.

  It's given in the question,

Therefore, EF = FG = (6x + 7)

And EF + FG = EG (By segment addition postulate)

Now substitute the values in the expression

(6x + 7) + (6x + 7) = (18x - 4)

12x + 14 = 18x - 4

12x - 18x = -14 - 4

-6x = -18

x = 3

            Therefore, the value of x is 3.
