All three angles equal 180. We are given that one of the three equals 45 so subtract that. You end up with 135. That 135 is split among two equal angles so just divide by two. The two angles both equal 67.5 degrees.

a. −108


b. −81


c. 81


d. 108

Answers

Answer:

1. d  2. a  3. d  4. a  5. a

Step-by-step explanation:

For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.

2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.

3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.

4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.

5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.

[12(x+3)-4]-2(x-1)+6]

Answers

10(x + 4)

Step-by-step explanation:

Simplify :

[12(x + 3) - 4] - 2(x - 1) + 6

= [12x + 36 - 4] - 2x + 2 + 6

= 12x - 2x + 36 - 4 + 2 + 6

= 10x + 32 + 8

= 10x + 40

= 10(x + 4)

What is the equation of the line that is parallel to 3x+4y=12 and passes though the point (4,8)

Answers

3x+4y=44
That’s the answer


Solve the simultaneous equations
5x - 4y = 19
x + 2y = 8

Answers

Answer:

x= 5 and y = 1.5

Step-by-step explanation:

5x -4y = 19

x + 2y = 8

let x = 8 - 2y...

5x - 4y = 19.......x = 8 -2y

5(8-2y) - 4y = 19

40 - 10y -4y= 19

40-14y = 19

-14y = 19-40

-14y = -21

y = 1.5

x = 8 - 2(1.5)

x = 8 - 3

x = 5

Thus, x is 5 and y is 1.5

Which statement is TRUE?

Answers

Answer:

it is a or d

Step-by-step explanation:

You have $6 to spend on lunch. The drinks cost $1.25 each and the salad
costs $0.20 per ounce. Write an equation in standard form that models
this situation.
1. 1.25 +.20x = 6
2. 1.25x + 20y = 6
3. 1.45x = 6
4. 1.25x + 6y = 20

Answers

Answer:

1. 1.25 + .20x = 6

Step-by-step explanation:

You will most likely just buy one drink and multiple ounces of salad with the 6 dollars you have to purchase a whole meal.

.20x, where x equals how many ounces you purchase

1.125 for the one drink

When set equal to 6 dollars you are able to find how much salad plus a drink you can purchase in total.

m∠y = 50 (Due to A)

m∠x = 50 (Due to F)

Step-by-step explanation:

Due to corresponding angles,

x = y = 50

Also, another thing... You wrote 60 degrees as your answer for the first part, you did a slight miscalculation.

180 - 130 = 50

So the answer for the first part is 50 degrees. However, the reasoning is correct!

Solve B=1/4m(s+z) for s

Answer:

[tex]s = \frac{-mz+4B}{m}[/tex]

Step-by-step explanation:

Step 1: Distribute.

[tex]B = \frac{1}{4}m * s + \frac{1}{4}m * z[/tex] [tex]B = \frac{1}{4}ms + \frac{1}{4}mz[/tex] [tex]\frac{1}{4}ms + \frac{1}{4}mz = B[/tex]

Step 2: Subtract 1/4(mz) from both sides.

[tex]\frac{1}{4}ms + \frac{1}{4}mz - \frac{1}{4}mz = B - \frac{1}{4}mz[/tex] [tex]\frac{1}{4}ms = -\frac{1}{4}mz + B[/tex]
