I HAVE THE SAME THING

Step-by-step explanation:

Answer:

1 Angle A is 44, 2 angle A is 20.

~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Equation for 1 is x + 45 + 82 + x + 65 = 180 x = -1 A = 44 Degrees

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Equation for 2 is x + 21 + 130 + x + 31 = 180  x = -1  Angle A = 20 Degree

Bye have a nice day :)

Step-by-step explanation:

let x be the number of adults and y number of childrens

so we have. x+y=100 people

and. 12*x+8*y=1056 dollars

x=100-y

replace 100-y to the second equation

12*(100-y)+8y=1056

1200-12y+8y=1056

1200-4y=1055

1200-1056=4y

144=4y

y=144/4=36

so x=100-y=100-36=64

so in this group were 64 adults and 36 childrens

In this group were 64 adults and 36 children.

In mathematics, a system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.

let x be the number of adults and y number of children

so we have. x + y = 100 people

and. 12 × x + 8 × y = 1056 dollars

x=100 - y

replace 100 - y to the second equation

12 × (100 - y) + 8y = 1056

1200 - 12y + 8y = 1056

1200 - 4y = 1055

1200 - 1056 = 4y

144 = 4y

y = 144/4 = 36

so x = 100 - y = 100 - 36 = 64

Hence, in this group were 64 adults and 36 children.

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

Since those two angles are corresponding that means they are equal to each other so we write an equation like this...

[tex]7x+9=8x+2[/tex]

Now we solve for x...

[tex]7x+9=8x+2\\9=x+2\\x=7[/tex]

And that's it x will equal 7.

Answer:

Step-by-step explanation:

When the second bus catches up to the first bus, this means that the distance they have travelled is equal.

So for bus 1, you know it travels at 40 miles per hour.

4pm = 0 miles

5pm = 40 miles

6 pm = 80 miles

7pm = 120 miles

For bus 2, you know it travels at 60 miles per hour

5pm = 0 miles

6pm = 60 miles

7pm = 120 miles.

So you can see that at 7pm, they will both have travelled 120 miles.

Step-by-step explanation:

First,, we should subtract the vacation price from her savings to get the base. That is 1835-1540=295. Then we can do 295/65,, and then we get 4  7/13. So,, she can only afford 4 weeks of these deductions in order to have enough money for her vacation.

Answer:8

Step-by-step explanation:

Area = Length x Width.

simple room measurement

Measure the length using the distance from one wall to the opposite wall.

Measure the width from wall to wall.

Add 2 to 4 inches to each side. This accounts for waste, doors and slanting walls. It’s easy to cut a little off for a perfect fit, but it’s impossible to add without creating unsightly seams.

Multiply the length times the width or enter those into the calculator above. This is your total square footage for that room.

Repeat this process for each room.

NOT SURE HOW MU

Answer:

oi hi how are you

Step-by-step explanation:

The required equation is y = -(3/2)x + 3 in slope-intercept form.

A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.

For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.

The equation is given in the question, as follows:

12x + 8y = 24

Isolate the variable of y for the above equation,

8y = - 12x + 24

Divided both sides by 8 into the equation,

y = - (12x)/8 + (24)/8

y = -(3/2)x + 3

This equation is in slope-intercept form.

Answer:

1. 7x

2. x+15

3. 18/x

Step-by-step explanation:

Assume the number is x because we don’t know what it is.

1. Product means multiplication so x * 7 equals 7x.

2. More means addition so x+15.

3. This one is easy. 18 divided by x = 18/x

Answer:

12800

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

In order to find the length and width necessary to find area, we need to look at the chart. By exmaining, we can see that the length is two units from top-to-bottom. We can also see that the width is 4 units from left-to-right. We can now multiply 4 times 2 to get our answer of 8.

Answer:

B. 8.0

Step-by-step explanation:

To figure out the area you just do length times width, and you find the two by counting the amount of squares they take up. The length is two, and the width is 4; therefore the area is 8

Answer:

- 17/10

Step-by-step explanation:

Answer:

Julio's number is 31.

Step-by-step explanation:

Okay, so -70 divided by -5 is 14.

14 plus 17 equals 31.

If you subtract 17 from 31, you get 14.

Then, if you multiply 14 times -5, you get -70.
