Expression

The fruit cost

Answers

Answer 1

Answer:

5($2.50)+3($1.50)=17

Step-by-step explanation:

you you just need to put up quantity by side of the bar pound it goes in the brackets that will give you the answer when you multiply that or something fruits value.

Answer 2

[tex]\boldsymbol{\$\,17}[/tex]

Algebraic ExpressionAn algebraic expression is one that is composed of integer constants, variables, and algebraic operations.A mathematical operation is a mathematical action. A mathematical operation includes addition, subtraction, multiplication, division, and calculating the root.

Cost of [tex]5[/tex] pounds of apples at [tex]\$2.50[/tex] per pound [tex]=\$\,(5\times 2.50)[/tex]

Cost of [tex]3[/tex] pounds of grapes at [tex]$1.50[/tex] per pound [tex]=\$\,(3\times 1.50)[/tex]

Therefore,

Total cost of the fruit [tex]=\$\,(5\times 2.50)+\$\,(3\times 1.50)[/tex]

                                   [tex]=\$\,12.5+\$\,4.5\\=\$\,17[/tex]

So, total cost of the fruit is [tex]\boldsymbol{\$\,17}[/tex]

Answers

Answer:

48

Step-by-step explanation:

4x=148+44

4x=192

x=48

Answer:

Step-by-step explanation:

there are 360 degrees inside any 4-sided polygon

so add all four angle measures and set equal to 360:

3x + x + 44 + 148 = 360

4x + 192 = 360

4x = 168

x = 42

check:

3(42) + 42 + 44 + 148 should equal 360

126 + 42 + 192 = 360

168 + 192 = 360

360 = 360

Answer:

slope of AB = 4

slope of CD = 4

Step-by-step explanation:

We simply use the slope formula for this;

The slope formula is;

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

for AB, we have;

m = (3+1)/(6-5) = 4

For CD, we have

m = (-1-3)/(1-2) = -4/-1 = 4

Dexter has 40 dimes and quarters. He has $5.20. How many quarters does he have?
How many dimes does he have?

Answers

Answer:

dimes = 32

quarters = 8

Step-by-step explanation:

set up a system of equations:

let d = # of dimes

let q = # of quarters

d + q = 40

.10d + .25q = 5.2

substitution method; let 'q' = 40 - d

.10d + .25(40 - d) = 5.2

.10d + 10 - .25d = 5.2

-.15d = -4.8

d = 32

q = 40 - 32 = 8

Answer:

Step-by-step explanation:

POSSIBLE POINTS: 100 A theater has group prices for tickets. The first ticket will cost $8 while each additional ticket will cost $5. Write a rule to model the situation. Then use the rule to find how the total cost of 13 tickets. Let n represent the number of tickets and c represent the total cost ​

Answers

Answer:

c = 8+5n

total cost of 13 tickets = $68

Step-by-step explanation:

c = 8 + 5(12)

c = 8 + 60

Creative Logic: Kevin is hiking on the trail and has to cross a rope bridge. He looks down at the raging river below and is suddenly very nervous. The bridge has 20 planks on it and every time he steps forwards five planks, he then steps backwards four planks. How many times must he do this to reach the other side?

Answers

Answer: 40 times

Step-by-step explanation:

Given: Total planks = 20

By using integers, Steps forward is represented by +5, Steps backward s represented by  -4.

After first set of two steps ( one forward another backward), 5-4 =1 step forward is captured.

For 20 planks , we require 20 such sets, i.e. he will do this 2x 20 times i.e. 40 times.

Hence, he will do this 40 times to reach the other side.

First, find the slope using the equation, y2 - y1 / x2 - x1

1-5 / 4 - - 4 = -4/8 =  -1/2

plug this into slope intercept form

y = -1/2x + b

Next use one of the points to find b using point-slope form. I will use (4,1)

y - y1 = m ( x - x1)

y - 1 = -1/2 (x - 4)

y -1 = -1/2x + 2

Answers

Answer:

For an equation like:

y = a*x + b

a is the slope, and this is the rate of change of the function.

For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.

Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.

Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden. Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam. This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears. Which batch of jam tasted more like cranberries?

Answers

Answer:

The batch of jam from this summer

Step-by-step explanation:

Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden.

For last summer

Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam.

Hence,

5 cup of pears = 3 cups of cranberries

1 cup of pears = x

Cross Multiply

5x = 3

x = 3/5

x = 0.6

1 cup of pears = 0.6 cup of cranberries

For this summer

This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears.

Hence,

8 cup of pears = 5 cups of cranberries

1 cup of pears = x

Cross Multiply

8x = 5

x = 5/8

x = 0.625

1 cup of pears = 0.625 cup of cranberries

From the above calculation we can see that the quantity of cranberries to 1 cup of pears from this summer is higher than that of last summer

Therefore, the batch of jam that tasted more like cranberries is the batch of jam from this summer

Answer:

This summer’s batch jam tasted more like cranberries.

6 identical toys weigh 1.8kg. a) convert 1.8kg to grams. b) what is the weight of one toy? Give your answer in grams. c) how much would 4 toys weigh? Give your answer in kilograms

Answers

Answer: a) 1800g b) 300g c) 1200g

Step-by-step explanation:

a) 1.8 x 1000 = 1800g

b) 1800g / 6 toys= 300g > the weight of one toy

c) 300g x 4 toys = 1200g / 1000 = 1.2 kg

Answer:

a. 1.8kg to grams

1000g =1kg

x =1.8kg

cross multiply

x = 1.8 x 1000

x= 1800g

b. weight of one toy

6 toys = 1800g

1 toy = 1800÷6

1 toy = 300g

c. 1kg = 300g

4toys = x

x = 4 x 300

x = 1200g

1200g to kilogram

1000g = 1kg

1200g = x

cross multiply

1000x = 1200

x = 1200÷1000

x = 1.2kg
