Answer 1
Answer: I think the easiest way to answer all of these is to just go ahead and find the equation of the line first. 

I'm pretty sure that by the time you reach this problem, you've learned to find
theequation of a line that passes through two given points.  You have twopoints:  (2, 100) and (5, 205).  The equation of the line through themis [ y = 35x + 30 ].

6).  The initial membership fee ... the cost for walking in the door and signing up,
before any months, is $30.  (Also the y-intercept.)

7).  The cost per month is $35.  (The slope of the line.)

8).  We already did that, up above.  [  y = 35x + 30 ].

9).  'x' in the equation is the number of months.
There are 12 months in one year.

y = 35(12) + 30 = $450

144 miles on 4.5 gallons

Answers

Answer:

32 miles per gallon.

Step-by-step explanation:

We are supposed to find unit rate for the given scenario.

144 miles on 4.5 gallons.

To find unit rate, we will divide 144 by 4.5 as:

\text{Unit rate}=\frac{144\text{ miles}}{\text{4.5 gallons}}

\text{Unit rate}=\frac{32\text{ miles}}{\text{gallon}}

Therefore, unit rate for our given situation is 32 miles per gallon.

144 miles on 4.5 gallons
Solution: 144mi                         4.5            32mi
             ------------   divided by             =  -------------

The function f(x) = 4.50x + 19 relates how much Sean pays to his scout club, f(x), to the number of patches, x, he earns in a month. What is the value and meaning of f(12)?

Answers

f(x)= 4.50 x +19

f(12)= 4.50(12) +19
f(12)= 54 +19

Ruby ate 1/3 of a pizza, and Angie ate 1/5 of the pizza. How much of the pizza did they eat in all?

Answers

Find common denominators. Multiply 5 to numerator and denominator of 1/3, and 3 to the numerator and denominator of 1/5

(1/3)(5/5) = 5/15

(1/5)(3/3) = 3/15

Add

5/15 + 3/15 = 8/15

Ruby and Angie ate 8/15 of the pizza.

hope this helps

i think it is 8/15 of the pizza

Find the lateral area of the solid figure 12/7 48 60 HELP

Answers

Answer:

60π in²

Step-by-step explanation:

Lateral surface area for a circular cone is given by the formula in the attached picture.

Lateral Surface Area,

=πr √( r² + h²)

=π (6) √( 6² + 8²)

= π6 √( 36 + 64)

= 6π √(100)

= 6π (10)

= 60π in²

Answer:

60 pi sq. in.

What is y+6x=11; 3x+2y=-2?

Answers

The answer is y=5 and x=83.


ヽ(◉ ͜ʖ◉)ノ







y+6x=11; 3x+2y=-26x+y+6x=11+6x(Add -6x to both sides)
y=6x+11
Substitute6x+11foryin3x+2y=−2
3x+2y=−2
3x+2(6x+11)=2
9x+22=−2(Simplify both sides of the equation)
9x+22+−22=−2+−22(Add -22 to both sides)
9x=24
9x/−9=−24/−9(Divide both sides by -9)
x=8/3
