Answer:

5x+8 because 7x-2x=5x and you cant do anything with the 9 so it just stays as a hang on at the end.

Step-by-step explanation:

Answer:

7x + 9 - 2x

We need to combine like terms (meaning terms that have the same power and variables);

(7x - 2x) + (9)

5x + 9

Answer:

57 students can still board

Step-by-step explanation:

If it carries 76 students total and 19 are already on, we must find the difference

This means we subtract

76 - 19 = 57

Hey there!

m + (n/1.2)

= 4.204  + (4.5/1.2)

= 4.204/1+ (4.5/1.2)

= 4.204/1 + 4.5/1.2

= 4.204 + 3.75

= 7.954

Therefore, your answer is: 7.954

Answer:

15 ounces

Step-by-step explanation:

0.75 tons is equal to 0.75 * 2000, or 1500, pounds (1 ton is 2000 pounds). Let x represent the number of ounces of fertilizer that should be applied. Set up a proportion:

[tex] \ \frac{1}{100} = \frac{x}{1500} [/tex]

Solving this for x, we have x = 15. So the landscaper should apply 15 ounces of fertilizer.

Answer:

Apple Cider is the better deal.

Step-by-step explanation:

1 gallon is 128 ounces.

8 times 4.23 is 33.84. So each purchase is 33.84 ounces. If you multiply 33.84  ounces by 4 you get 135.36. (I did 4 because 3 would be too little to make a gallon).

After that you need to multiply 2.39 and 4. You need to do this because it will tell you the cost. That will come out to 9.56$.

So, that is why the apple cider is a better deal, because it is 7$ and the other would be 9.56$.

Answer:

Solve for x = 17

Solve for y = 9

The value of x and y from the figure are 17 and 7 respectively

From the given diagram, we are told that  I ll m, hence:

Get the value of x

5x-3x = -4 + 38

2x = 34

x = 34/2

x = 17

Also from the triangle:

7y - 20 + 5x - 38 = 90

7y + 5x -58 = 90

7y + 5(17) = 90 + 58

7y + 85= 148

7y = 148 - 85

7y = 63

y = 63/7

y = 9

Hence the value of x and y from the figure are 17 and 7 respectively

Answer:

x = 6

Step-by-step explanation:

i think of a number multiply it by 3 and add 4 i get 22.

x = a number

x is being multiplied by 3 (3*x or 3x), thening add 4 is equal to 22.

3x + 4 = 22

    - 4    - 4

3x = 18

/3      /3

x = 6

Therefore, the unknown number is 6.

x = 6.5

Explanation:

[tex]\sf 23 - 2x = 10[/tex]

subtract 23 from both sides

[tex]\rightarrow \sf 23-2x-23=10-23[/tex]

simplify the following

[tex]\rightarrow \sf -2x=-13[/tex]

divide both sides by -2

[tex]\rightarrow \sf \dfrac{-2x}{-2}=\dfrac{-13}{-2}[/tex]

simplify

[tex]\rightarrow \sf x=\dfrac{13}{2}[/tex]

in decimals

[tex]\sf \rightarrow x = 6.5[/tex]

Recheck the following

[tex]\hookrightarrow \mathrm{23 - 2(6.5) = 10}[/tex]

[tex]\hookrightarrow \mathrm{23 -13 = 10}[/tex]

[tex]\hookrightarrow \mathrm{10 = 10}[/tex]

L.H.S = R.H.S thus. x = 6.5

The point that is marked on the number line is  - 0.875.

According to the number line diagram, the right side after zero is the positive side while the left side before zero is the negative side.

The marked point is before zero, therefore, the marked point on the number line is surely a negative number.

Each step in the number line represents a step of 0.125.

Hence, the marked point represents 7 steps from zero, therefore, the marked point is  -0.875.

Answer:

8750

Explanation:

There are 5/5 math teachers in the university. 3/5 of them did not want to become math teachers which means 2/5 of the math teachers is equal to 3500.

3500=2/5

divide 3500 by 2 to get 1/5 of the math teachers.

3550/2=1750

1750 is 1/5 of the math teachers.

multiply 1750 by 5 to get 5/5 of the math teachers

1750*5= 8750
