Combine like terms to simplify the expression below.

12(6x+4)+5x−8

Answer: 9.9 yards

Step-by-step explanation: Since we know that the legs of the right triangle both measure 7 yards, we can use the Pythagorean theorem to find the length of the hypotenuse, which is the longest side of the right triangle.

According to the Pythagorean theorem, the square of the hypotenuse equals the sum of the squares of the legs. In this case, we have:

c^2 = 7^2 + 7^2 c^2 = 49 + 49 c^2 = 98

To find the length of the hypotenuse, we need to take the square root of both sides of the equation:

c = √98

Using a calculator, we can find that √98 is approximately 9.9. Therefore, the length of the hypotenuse is approximately 9.9 yards.

The answer is C. 9.9 yards.

Answer:

2.5 hours (2 and 1/2)

Step-by-step explanation:

Every 1 hour, Erin runs 10 miles and so on. The ratio is 1:10 (2:20, 3:30, etc.) 25 is 20+5, and 5 is considered 1/2 of 10, so it would count as 0.5 (or 1/2). So in 2.5 hours Erin will run 25 miles. Hope it helped :>

Answer: hope this helps ♡

1.) x = -21

2.) x = 18

3.) x = 3

Step-by-step explanation:

(minus&minus = plus)       (minus&plus = minus)        (plus&minus = minus)

1.) 25 - 3x = 88

25 - 25 - 3x = 88 - 25

-3x = 63

-3x ÷ 3 = 63 ÷ 3

-x = 21 → x = -21

2.) -11 = 7 - x

-11 - 7 = 7 -7 -x

-18 = -x

18 = x → x = 18

3.) 95 = -4 + 33x​

95 + 4 = -4 + 4 + 33x

99 = 33x

99 ÷ 33 = 33x ÷ 33

3 = x → x = 3

Answer:

18π cubic inches

Step-by-step explanation:

First, we need to find the radius of the cone, which is half of the diameter.

radius = diameter/2 = 6/2 = 3 inches

The formula for the volume of a cone is:

V = 1/3 × π × r^2 × h

where r is the radius of the base of the cone, and h is the height of the cone.

Substituting the values we get:

V = 1/3 × π × 3^2 × 6

V = 1/3 × π × 9 × 6

V = π × 18

Answer:

Step-by-step explanation

For the first sum you nee to find the same coefficient or add or subtract a number

[tex]-x^3 -2x -7[/tex]

This the simplified version of the sum above. I have basically subtracted -2x^3 by x^3 to make -x^3. Then I have subtracted -3x and x to make -2x. Finally I have added -4 and -3 as the rule suggests to add two numerals the minus symbol on both of them.

The next sum we have to simplify both numerals so we know if both sum’s answer are

[tex]-x^3 -2x -7-x^3 -2x -7[/tex]

After simplifying them,  both of them have the same answer, so the statement is true. To explain this, we could say that the sums were basically rotated around to trick us but the answer is still the same

Answer: $9602.50

Step-by-step explanation:

The initial price is $8,350. If the price is marked up by 15%, then the retail price will be 115%, or 1.15 times, the initial price.

[tex]8,350 * 1.15 = 9602.5[/tex]

One mile is equal to 1,760 yards. Therefore, two and one-half miles can be calculated as:

2.5 miles * 1,760 yards/mile = 4,400 yards

So, the answer is A) 4,400 yards.

Answer: 25 miles

Step-by-step explanation:

Answer:

The answer is 25.

Step-by-step explanation:

Since the scale shows 10 miles for every 2 inches, you can easily figure out that it is 5 miles per inch.

Now, it says two towns are 5 inches apart. With the previous information, you can either multiply 5 inches by 5 miles per inch or think deeper.

Thinking deeper: If there is 4 inches, that is 20 miles. Adding another inch doesn’t add another ten. It adds half of ten and half of ten in 5. 20+5=25

Step-by-step explanation:

mangos: m = 108

portugals:  p

oranges:     o = 3p

108 + p + 3p = 540

108 + 4p = 540

4p = 540-108 = 432

p = 432/4 = 108

o = 3p = 3(108) = 324

324/108 = 3  there are 3 times more oranges than portugals

Answer:

1620

Step-by-step explanation:

540 X 3 = 1620

Answer: The answer is -6.

Step-by-step explanation:

The first step in solving -X²= - 36 is to simplify the expression. Then, divide both sides by the same factor. You'll get X² - 36 = 0.

After that, you need to use the quadratic formula. Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula. a=1, b=0, and c=-36.

Finally, you need to simplify the expression. First, evaluate the exponent. Then multiply the numbers. After that, Add the numbers and evaluate the square root. Add zero, and then multiply the numbers again. You get +12/2, which simplifies into X = 6. Add the negative, and you get X = -6.

Answer:

Step-by-step explanation:

Infinitely many.

The two equations are the same yet formatted differently. Because these lines will overlap each other, the answer is infinitely many.

Answer: y=-7

Step-by-step explanation:

solve 5x+2y =-4 for x

Add -2y to both sides

divide both sides by five
substitue -2/5y +-4/5 for x in 3X +10 Y equals -64

44/5 + -12/5 equals -64

Simply both sides

add 12/5 to both sides

Divided by 44/5
y= -7

Answer:

Hence The Value of Y=-2 at the intersecting point

Step-by-step explanation:

Given the equation

5x+2y=-4 and 3x+10y=-64

are intersected at X=2 to find the value of y

solution the equation 5x+2y=-4 and 3x+10y=-64

are intersect at x=2 means x=2 satisfied both equations so x=2 put in the

1st equation

5 x 2+2y=-4

2y=-4 -1 0= -14

y= -7

Answer: incorrect i cannot read.

anyways, the answer is c, the third bubble.

and 20 minutes

you get this from needing to find the total minutes spent, in order to do so, you need to add 25, to whatever number (or t) to equal 45

as for the minutes, you do the exact opposite, and subtract 25 from 45, to get 20

Answer:

x=12.5% (hope this right if not I am so sorry)

Answer Explanation:

let x%= annual interest rate

deposit = $800

interest earning period = 24 months = 24/12 years

interest earned = $200

so $200 = $800 * x /100* 24/12

200 = 800 * x/100 * 2

solve for x,

x = 12.5% per annum

Answer: X = 12.5%
