the tennis team is having a bake sale. cookies sell for $1 each, and cupcakes are $3 each. If Connie spends $15 for 7 items, how many cupcakes did she buy?

Complete question :

a pet store had a special offer this weekend. for every $120 that customers spend, $3 is donated to a pet rescue program. How much do customers have to spend in order to raise $1000 for the pet rescue program?

Answer:

$40000

Step-by-step explanation:

Offer :

For every $120 spent ; $3 is donated

In other to raise $1000 ; $x would have to be spent ; we can obtain the value of x using cross multiplication ;

$120 = $3

$x = $1000

Cross multiply

$(120 * 1000) = $3 * x

$120000 = $3x

x = 120000 / 3

x = 40,000

Hence, in other to raise $1000 ; $40000 would have to be spent by customers.

Answer:

4

Step-by-step explanation:

First, solve for x:

4 + 2(3x - 4) = 8

4 + 6x - 8 = 8

6x = 12

x = 2

Now, plug x into 4x - 4:

4(2) - 4 => 8 - 4 = 4

Answer:

8 fifty cents coin.

Step-by-step explanation:

Let's assign variable for the unknown number of coins.

Let there are 'x' number of $1 coins

'y' number of 20 cent coins

'z' number of 50 cent coints.

Totally there are 26 coins.

So, x+y+z=26

Now, there are 6 more $1 coins than 20-cent coins.

We can set up equation for this as

x= y+6

Now, total value of these coins is $17.20

We can setup equation as

100 x+20 y+50 z=1720

Now, substitute x as y+6

100(y+6) +20 y+50 z =1720

Distribute the 100 to get rid ( )

100 y+600 +20 y+50 z=1720

Combine like terms

120 y+50 z= 1120

Keep this equation as it is.

Plug in x as y+6 into x+y+z=26

y+6+y+z=26

2y+z=20

Now, take the two equations

2y+z=20

120y+50z=1120

Multiply first equation by -60 to eliminate the y terms when we add them.

-120y-60z=-1200

120y+50z= 1120

-------------------------

     -10z =-80

Divide both sides by -10

z=8

Now, plug in z as 8 into 2y+z=20

2y+8 =20

Subtract both sides 8

2y=12

Divide both sides by 2

y=6

Now, plug in y, z values into the first equation.

x+6+8=26

x+14=26

Subtract both sides 14

x=12

So, there are eight 50-cent coins.

Answer:

(2,-2)

Step-by-step explanation:

Answer:

2(2x-4)=3(x+4)

4x-8=3x+12

4x-3x=12+8

x=20

Answer:

C

Step-by-step explanation:

3x-y=14

4x+y=21

add

7x=35

x=35/7=5

4×5+y=21

y=21-20=1

so (5,1 ) is the solution.

2p-4+16=5p-9

-3p-4+16=-9

-3p-4=16+-9

And if you can solve from there cuz that's a lot of mental math for me. if u see these:() always distribute whatever is before it.

Answer:

x² - x - 6

Step-by-step explanation:

Given

(x + 2)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 3) + 2(x - 3) ← distribute parenthesis

= x² - 3x + 2x - 6 ← collect like terms

= x² - x - 6

Answer:

Pentagonal Prism

Answer:

1/12

Step-by-step explanation:

The total number is 12 (assuming the dice would be rolled 12 times) 7 is a number in the range and it will appear once in the 12 rolls because each number shows each time. 1 (how many times 7 will show)/ 12(total number of rolls)

Probability of [tex]7[/tex] when a dice (showing numbers 1 throught 7) is thrown is equal to [tex]\boldsymbol{\frac{7}{12}}[/tex] as a dice is rolled.

Probability refers to chances of occurrence of any event.

Value of probability lies in the interval [tex]\boldsymbol{\left [ 0,1 \right ]}[/tex]

Total number of numbers on a dice [tex]=12[/tex]

Probability is equal to number of favorable outcomes divided by the total number of outcomes.

Probability of [tex]7=\frac{7}{12}[/tex]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the Equation :

(5/8)m = 25

The first step to take with this kind of equation is to multiply both sides by the denominator, 8

5m/8 * 8 = 25 *8

5m = 200

Then, we can divide both sides by 5 in other to isolate m

5m / 5 = 200 / 5

m = 40

Answer: m+40

Step-by-step explanation:

Given the Equation :

(5/8)m = 25

The first step to take with this kind of equation is to multiply both sides by the denominator, 8

5m/8 * 8 = 25 *8

5m = 200

Then, we can divide both sides by 5 in other to isolate m

5m / 5 = 200 / 5

m = 40
