7(x+1)-4x+19 how to solve

Answer:

6

Step-by-step explanation:

Answer:

x = - 8/23

y = 40/23

Step-by-step explanation:

-5x- y = 0

and

-8x+3y = 8

The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.

-5x-y = 0

-y = 5x

y = - 5x

Now you can take this y value and plug it into the section equation.

-8x + 3(-5x) = 8

-8x - 15x = 8

-23x = 8

x = - (8/23)

Once you get the x value you can plug it back into equation one to get y's value

-5*-(8/23)  - y = 0

40/23 - y = 0

y = 40/23

Answer:

C. 35 sq. units

Step-by-step explanation:

in order to find the area of a triangle you have to use the formula

1/2 b h

b as in base

h as in height

so if we use the measurements on the triangle and we plug that in we will get

1/2 x 14 (the base) x 5 (the height)

therefore giving us 35 sq. units.

hope this helps!

Answer:

112:x

11200/80=x

x= 140

40% increase

Answer:

29%

Step-by-step explanation:

112-80=32

increase ÷ original × 100 %

= 32÷112×100%

≈29% (corrected to the nearest whole number)

Step-by-step explanation:

[tex] \tt{30.16 = 17.56 + 5x} [/tex]

Swap the sides of the equation :

⤑ [tex] \tt{17.56 + 5x = 30.16}[/tex]

We want to remove the 17.56 first.

Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :

⤑ [tex] \tt{5x + 17.56 - 17.56 = 30.16 - 17.56}[/tex]

Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.

⤑ [tex] \tt{5x = 12.6}[/tex]

Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.

⤑ [tex] \tt{ \frac{5x}{5} = \frac{12.6}{5}} [/tex]

Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

[tex] \pink{ \boxed{ \boxed { \tt{Our \: final \: answer : \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}[/tex]

Hope I helped ! ♡

Have a wonderful day / night ! ツ

Answer:

a = 86y

Step-by-step explanation:

Given:

Number of applicants per year = 86

Find:

Equation represent total applicants

Computation:

Assume;

Total number of years = y

Total number of applicants = a

So,

Total number of applicants = Number of applicants per year x Total number of years

a = 86 x y

a = 86y

Answer:

100

Step-by-step explanation:

"Percent" or "%" means "out of 100" or "per 100".

Therefore 20% can be written as  20 /100

Therefore, 20 is 20% of  100

Answer:

3.45

Step-by-step explanation:

if 4 pints are 13.80 you would have to divided 13.80 by 4 and 4 by 4 to get 1 over blank. The denominator would be 3.45 which would be the amount 1 pint cost. If you don't want to do it as fractions you can simply divide 13.80 by 4.

Answer: 1/14, 2/28.

Step-by-step explanation:

2/7 x 0.25 =

Convert 0.25 into a fraction.

0.25 = 1/4.

Multiply the numerators together and then multiply the denominators with each other.

1/4 x 2/7 = 2/28.

Therefore, the answer is 2/28, but it can also be simplified to 1/14. So the answer is the first one, or 1/14.

Answer:

1/14 or A

Step-by-step explanation:

0.25 as a fraction is 1/4

1/4 x 2/7 = 2/28, simplify to become 1/14, and there is your answer

The correct option regarding the average rate of change for glass is given by:

c. From 1970 to 1980, the number of pounds of glass per person per day increased by 0.002 per year.

It is given by the change in the output divided by the change in the input.

Looking at the table, in the 10 years from 1970 to 1980, the amount of glass changed from 0.34 pounds to 0.36 pounds, hence the rate is given by:

r = (0.36 - 0.34)/10 = 0.02/10 = 0.002.

Which means that option c is correct.
