Answer:

2.3a + 0.8a =

2.3

+ 0.8

________

3.1

________

So therefore, 2.3a + 0.8a = 3.1a

Answer:

a= -3

Step-by-step explanation:

first distrubute the parenthesis -2(a-3)

-2a+ 6= 12

then move the like terms

6 becomes -6 and subtract to both sides so 6-6 cancels out and you are left with 12-6 which gives you 6

then you have -2a = 6

lastly divide on both sides and you get

-2a÷ -2 (cancels out)

6÷ -2

and the answer is

a= -3

Answer: For G the answer is x=30, for H x is 30

Step-by-step explanation:

G. The square means 90 degrees and the equation would be 90+3x=180. Subtract 90 from both sides would give you 3x=90 and divide it by 3 would give you x=30

H. The two lines means that both sides are congruent and so 75x2=150 150+x=180 subtract 150 from both sides would give you x=30

Answer:

it would take laurel 56 minutes to run 7 miles.

Step-by-step explanation:

She has to run 7 miles, so if she can run 3 in 24 minutes, you can double that time to 48 minutes to run 6 miles, on top of adding another 8 minutes due to 1/3 of 24 (the third being equal to 1 mile since 24 is 3 miles) being 8, leaving you with 56 minutes for her 7 mile run.

Answer:

The slope of the line is 4

Step-by-step explanation:

You use the equation Y2 - Y1/ X2 -X1 to find the slope.

-61-(-37)/-32 - (-26)

-24/-6

4

Answer:

The answer is 4

The measure of angle TQR is 47 degrees and the measure of angle TRS is 133 degrees

In order to determine the measure of each angle, the value of x has to be determined first

The sum of angles on a straight line is 180 degrees

Thus : (3x + 5)° + (10x - 7)° = 180°

3x + 5 + 10x - 7 = 180

combine similar terms

3x + 10x = 180 - 5 + 7

add similar terms

13x = 182

divide both sides of the equation by 13

x = 14°

Substitute for x in (3x + 5)° and (10x - 7)°

(3x + 5)° = 3(14) + 5 = 47°

(10x - 7)° = 10(14) - 7 = 133°

Answer:

12.43 function step by step explanation

Answer:

Step-by-step explanation:

First find the LCM of 30, 16. This will give the common number of sausages and bread rolls

30 = 2 *  3 * 5

16 = 2 * 2 * 2 * 2

LCM = 2* 2 * 2 * 2 * 3 * 5 = 240

240 sausages and 240 bread rolls

Number of Sausage pack = 240 ÷ number of sausages in a pack

                                           = 240 ÷ 16

                                           = 15

Number of bread roll pack = 240 ÷ number of bread rolls in a pack

                                           = 240 ÷ 30

                                           = 8

Jenny should buy 8 pack of bread rolls and 15 pack of sausage

2)  LCM of  2 , 5 , 8 = 40

Tom, Sam, Matt  will hit their drum same at 40 minutes

Number of beats hit by Tom before reaching 40 minutes = 40/2 =20 hits

Number of beats hit by Sam before reaching 40 minutes = 40/5 = 8 hits

Number of beats hit by Matt before reaching 40 minutes = 40/8 = 5 hits

1)   1/243 (Fraction)

2)   Equal to 1

3)   1/x^7 (1 over x, x to the power of 7)

4)   4

5)   Equal to 1

===========================================================

Explanation:

To find the slope, all you need are two points.

Pick any two columns to form the two points. Once you have your two points, use the slope formula

I'll use the first two columns

m = (y2-y1)/(x2-x1)

m = (12.2-13)/(4-0)

m = -0.8/4

m = -0.2 is the slope

The y intercept is b = 13 since x = 0 leads to y = 13 (column 1)

With m = -0.2 and b = 13, we go from y = mx+b to y = -0.2x+13

Answer:

107

Step-by-step explanation:

it looks like a right angle

Answer:

The answer is 107 degrees.

Step-by-step explanation:

The sum of all the angle of a triangle must equal 180 degrees. That being said if you grab 180 and subract 44 and 29 from it you get 107 degrees. 107+44+29=180. If this did not equal 180 the answer would be wrong but since it does it is right.

Answer: x=6

Step-by-step explanation:

Just think about how the problem is half

The value of x is 6.

Here,

M is the midpoint of PQ.

PM = 5 x + 6

PQ = 76

What is midpoint of line?

The midpoint is the middle point of a line segment. It is equidistant from both end points.

Now,

M is the midpoint of PQ.

Hence, PM = MQ

And, PQ = PM + MQ

     ⇒  PQ = 2 PM

     ⇒ 76 = 2 (5x + 8)

     ⇒ 38 = 5x + 8

     ⇒ 5x = 30

     ⇒  x  = 6

Hence , The value of x is 6.

Answer:

AC=22

Step-by-step explanation:

The measure of the Length of AC is; 35

We are given;

ac = 5x

ab = 12

bc = 3x + 2

ab + bc = ac

Thus;

12 + 3x + 2 = 5x

14 + 3x = 5x

Subtract 3x from both sides to get;

5x - 3x = 14

2x = 14

x = 14/2

Answer:

30*

Step-by-step explanation:

If ABD is 105* then it would be <ABC+<CBD=105*. We know that <ABC is 75* so we can fill that in. 75*+<CBD=105*. Then we solve.

75* + <CBD = 105*

-75*                  -75*

<CBD=30*

Answer:

Three sheets will be left over.

Step-by-step explanation:

Well, if you have 80 sheets of paper, and seven students need it, you would first divide the 80 sheets to the seven students using the equation 80 ÷ 7 = 11.4. You won't be giving fractions of paper to the students so you would round to 11. If each of the seven students gets 11 sheets of paper, 77 sheets will have been used. 80 - 77 = 3. So, there will be three sheets left over.
