Answer 1

Answer:

21

Step-by-step explanation:

Hey There

So remember all of the angles in a triangle add up to equal 180

The exterior angle is equal to the missing interior angle because they are vertical angles

so 180 = 2x + 6 + x + 9 + 129

step 1 combine like terms

6+9+129=144

2x+x=3x

now we have

180=144+3x

step 2 subtract each side by 144

180-144=36

now we have

3x=36

step 3 divide each side by 3

36/3=12

Now we just plug in 12 to x+9

12+9=21

so we can conclude that angle A = 21

Answer pls im desperate (10 pts) (how many solutions does this have)

Answers

Answer:

Step-by-step explanation:

Left side

4x + 2x - 10

6x - 10

Right side

6x - 12

Eventually when you equate these sides, you will get an absurd answer because the 6x term will be subtracted out on both sides

that means you get -10 = - 12

which destroys the whole concept of equality. There is no solution.

13 Candy bars weigh 26 ounces what is the weight of 35 candy bars?

Answers

Answer:

70 ounces

Step-by-step explanation:

26 ounces divided by 13 candy bars is 2 ounces each.

2 ounces times 35 bars would be 70 ounces.

70/16= 4lb, 6oz

ANSWER: 70 ounces or about 4.38 pounds

Step-by-step: What we have is a ratio. 13:26 ☞︎ 1:2 —— So for every candy bar, it’s 2 ounces. Now that we know this we can do 35•2 which would get us to 70 ounces or 4.375 pounds. So 35:70 — — Hope this helped — wasn’t given any answer choices so I went off my knowledge!

which of the following is parallel to the line y=3/4x+7
y=-4/3x+7
y=-3/4x+7

Answers

Are you sure you wrote the question corrcetly?

For something to be parallel their slopes have to be equal but their y-intercepts need to be different.

since your equation equals y=3/4x+7 that would mean that 3/4 is the slope.

so an answer with a slope of 3/4x and a y-intercept not equal to 7 would be the correct answer.

Answer:

  J  3/4 cup

Step-by-step explanation:

Step 1: read and understand the question.

  The question is giving you amounts of flour and 2 types of sugar.

  The question is asking for a difference between two quantities:

the amount of flour (2 1/4 cups)the combined amount of sugar (3/4 cup white, 3/4 cup brown)

Step 2: determine the relations you need to use to solve the problem

   You need the combined amount of sugar, which you find by adding the quantities of each of the kinds.

  3/4 cup white + 3/4 cup brown = 6/4 cup sugar combined

 You need the difference of that quantity from the quantity of flour, which you find by performing subtraction:

  flour - sugar = (2 1/4) - (6/4) . . . . cups

Step 3: Use your knowledge of arithmetic.

  (2 1/4) -(6/4) = 9/4 -6/4 = (9 -6)/4 = 3/4

Step 4: Answer the question that was asked.

  The difference between the flour and sugar amounts is 3/4 cup.

it is y=-1/5 - 1 since it intercepts at -1 on the y line

Answer:

y = -1/5x - 1

Step-by-step explanation:

The line crosses the y axis at -1, making it the y-intercept.

Since the line is going downwards from left to right, we know that it is a negative slope.

The line goes down one and 5 right. That makes the slope -1/5.

The equation is y = -1/5x - 1
