Please help me . What is x equal to?
1. 2 (x+3) =10
2. 2 (x+3)=9+x
3. 2(2x+1) = 3x+8
4. 2(2x+3) =X+9

Answers

Answer 1

Answer:

1. x = 2

2. x = 6

3. x = 6

4. x = 1

Step-by-step explanation:  i think thats it

Answer 2

Answer:

x = 2, x = 3, x = 6, x = 1

Step-by-step explanation:

1

2(x + 3) = 10 ( divide both sides by 2 )

x + 3 = 5 ( subtract 3 from both sides )

x = 2

2

2(x + 3) = 9 + x ← distribute parenthesis on left side

2x + 6 = 9 + x ( subtract x from both sides )

x + 6 = 9 ( subtract 6 from both sides )

x = 3

3

2(2x + 1) = 3x + 8 ← distribute parenthesis on left side

4x + 2 = 3x + 8 ( subtract 3x from both sides )

x + 2 = 8 ( subtract 2 from both sides )

x = 6

4

2(2x + 3) = x + 9 ← distribute parenthesis on left side

4x + 6 = x + 9 ( subtract x from both sides )

3x + 6 = 9 ( subtract 6 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

1/10 of the counters in a bag are blue. 1/2 of the counters are red. 2/5 of the counters are yellow. Which of the ratios below shows the ratio of blue to red to yellow?

Answers

Answer:

well 1/10 are blue, 5/10 are red, and 4/10 are yellow.

1/10 blue

5/10 red

4/10 yellow

I don't really know how to answer this question but I hope me converting the ratios helps :)

Step-by-step explanation:

Given: 1/10 blue
1/2 red
2/5 yellow


First, make it so that each if their whole (denominator, or the right side) is equal.

We already know that 2 and 5 are common factors of 10, so we get them to the number 10 by equal multiplication.


1/10 - blue
1/2(5) = 5/10 - red
2/5(2) = 4/10 - yellow

Now just take their numbers in order.

If a man walks at the rate of 3 feet per second, how many minutes will it take him to walk 5760 feet?

Answers

Answer:

32 minutes

Step-by-step explanation:

There are 60 seconds in a minute

That means we will need to know how many feet he walks in a minute

So we would do 3 x 60 which equals 180 so he walks 180 ft per miute

Now we need to figure out how many minutes it took for him to walk 5760 ft.

So we would do 5760 ÷ 180 which equals 32

So the aswer is 32 minutes for him to walk 5760 ft.

Hope this helps

In the number 3.9928, how does the value of the 9 in the tenths place compare to the value of the 9 in the hundredths place? Drag and drop a fraction into the box to correctly complete the statement. The value of the 9 in the tenths place is Response area the value of the 9 in the hundredths place.

Answers

Answer:

the 9 in the tenths place is 10 times bigger than the one in the hundredths place

Step-by-step explanation:

The value of the 9 in the tenth place is "10 times" the value of the 9 in the hundredth place.

What is the place value strategy?

Place value strategies are defined as math strategies that use to assist you in resolving your elementary math problems, using your place values, such as tens and hundreds.

The decimal we are examining is 3.9928.

The 9 in tenth place has a value of 0.9.

The value of 9 in the hundredth place is 0.09

The fraction of the 9 in the tenth place is now the 9 in the hundredth place.

To get this, simply multiply the value of 9 in the hundredth place by the value of 9 in the tenth place.

Mathematically, that would be;

0.09/0.9 = 0.1 = 1/10

This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place

So you can complete the statement by dragging and dropping "10 times" into the response area.

In trapezoid MNPQ shown below, MN || QP, m&M = 108°, m&P = 4x - 5, and
mxQ = 3x + 21. What is the number of degrees in m«N.

Answers

Answer:

Answer:

The answer is below

Step-by-step explanation:

A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base. Also, the angles on the same leg of a trapezoid (adjacent angles) are supplementary (add up to 180°).

In trapezoid MNPQ:

∠M + ∠Q = 180° (angles on the same leg are supplementary)

108 + (3x + 21) = 180

3x + 129 = 180

3x = 51

x = 17

Also:

∠N + ∠P = 180° (angles on the same leg are supplementary)

∠N + (4x - 15) = 180

∠N = 180 - (4x - 15)

∠N = 180 - 4x + 15

∠N = 195 - 4x

substitute x = 17°:

∠N = 195 - 4(17)

∠N = 127°

The length of a rectangle is 5 inches longer than it is wide. If the perimeter is 38 inches, what are the dimensions of the rectangle?

The width, or shorter side is ______
inches.

The length, or longer side is _____
inches.

Answers

Answer:

shorter side = 7 in

longer side = 12 in

Step-by-step explanation:

Let w = width

then w + 5 = length

The perimeter of the rectangle = 2 widths + 2 lengths.

So, w + w + w + 5 + w + 5 = 38  or 2w +2(w + 5) = 38 are two ways to write the equation to solve the problem.

Now 4w + 10 = 38

4w = 28

w = 7

w + 5 = 7 + 5 = 12

shorter side = 7 in

longer side = 12 in

Check:  7 + 7 + 12 + 12 = 38 = perimeter

Answer:

  12.  median: AD; altitude: CE; midsegment: none

  13.  x = 2

Step-by-step explanation:

12. The median joins a vertex with the midpoint of the opposite side. Point D is identified as the midpoint of BC, so AD is the median.

An altitude is a segment from a vertex that is perpendicular to the opposite side. CE is an altitude of this triangle.

A midsegment joins midpoints of adjacent sides of the triangle. Only one midpoint (D) is identified in this triangle, so no midsegment can be named.

Additional comment: BF is an angle bisector. Perhaps that is what is intended in part (c). You may want to report this question to your teacher.

13. The base segment is twice the length of the midsegment:
