Answers

Answer:

Bagels are 4 and Muffins are 2

Step-by-step explanation:

solve the system of equations

Answer:

Bagels are 4 and the muffins are 2 or the first answer

Step-by-step explanation:

2b+m=10

3b+m=14

we can subtract the equations

-b=-4

multiply both sides by -1 to get

b=4 meaning a bagel is four dollars

we can then subsitute this

2(4)+m=10

8+m=10

subtract 8 from both sides

m=2

subsitute these into the second equation to check

3(4)+(2)=14

12+2=14

14=14

Therefore the answer is Bagels are 4 and the muffins are 2 or the first answer

Answers

Answer:

215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left

Step-by-step explanation:

we have 5,814 meters of rope and we are told to calculate the number of 27 meters sections that we can cut:

you have to divide 5,814 meters by 27 meters = 215.333

that means that you have 215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left (0.333 x 27 = 9)

Answers

Answer:

1.25

Step-by-step explanation:

First we should fill in what we know. They mentioned that the y would be the numerator (# on the top) and the x would be the denominator (# in the bottom).

[tex]\frac{3}{24} =\frac{y}{10}[/tex]         <----  This will be your proportion

Now we will cross multiply and make a equation. So we will do 3 * 10 which equals 30 and then 24 * y which is 24y. So now our equation will look like this.

[tex]30=24y\\y=1.25[/tex]

Then when you solve the equation you'll get 1.25

8. Aaron and Zelly want to rent a tandem bike so that

they can ride together. The rental for a tandem bike is

$18.50 per hour plus $3 for each helmet. Aaron and

Zelly have $80 to spend on the bike rental. Which

equation can be used to find h, the number of hours

they can rent a tandem bike? (hint: if you do not know

what a tandem bike is, you need to look it up!)

80 = 6h + 18.50

80 = 18.50h + 3

80 = 18.50h + 6

80 = 3h + 18.50

Answers

Answer:

[tex]80 = 18.50h + 6[/tex]

Step-by-step explanation:

Given

[tex]Amount = \$80[/tex]

[tex]Rent = \$18.50[/tex] per hour

[tex]Helmet = \$3.0[/tex]

[tex]Individuals =2[/tex]

Required

Derive an expression for the scenario

A tandem bike allows 2 individuals to ride on it at a time.

So, they will only pay for one rental fee because both can ride on it at the same time.

However, they need to get separate helmets.

For Helmets, they will spend:

[tex]\$3 * 2 =\$ 6[/tex]

For Rental, they will spend

[tex]\$18.50 * h = \$18.50h[/tex] for h hours.

[tex]Total = Rentals + Helmets[/tex]

[tex]Total = 18.50h + 6[/tex]

Recall that they have just $80 to spend

So, substitute 80 for total

[tex]80 = 18.50h + 6[/tex]

Hence, option C answers the question.

Describe the graph of y = |x - 2| + 4

Answers

Answer:

Step-by-step explanation:

Note that this function resembles the absolute value function y = |x|.

The graph of y = |x| has its vertex at (0, 0) and opens up in a v-shape.

The graph of y = |x - 2| looks the same as that of y = |x|, but the entire graph has been translated 2 units to the right.

The graph of y = |x - 2| + 4 is that of y = |x - 2|, translated 4 units up.
