you purchase 3 t-shirts and a booklet for 90$. the booklet cost 15. how much is each t-shirt? please help ! thank u

Answers

Answer:

each t-shirt was $25

Step-by-step explanation:

90 minus 15 = 75

75 divided by 3 equals 25

Answer:

25

Step-by-step explanation:

3t+15=90

3t=75

t=25

t represents the price for one t-shirt. 90 is the total amount and if the booklet is 15 dollars, altogether they equal 90. With this equation you are trying to isolate the variable (t), so subtract 15 because the opposite of 15 is -15. Then divide that by 3 because 3t is also 3 times t and the opposite of times is division.

I’ve been able to figure out the rest of the questions but this one has me stumped. I need to solve for x. Can someone please write the steps down so I can learn what to do?

Answers

explanation:
x+91 and x+111 are supplementary angles (they add up to 180), so you would set an equation by adding both of them to equal 180:
x + 91 + x + 111 = 180
add like terms
2x + 202 = 180
subtract 202 from both sides
2x = -22
divide both sides by 2 to get the answer:
x = -11

Answer:

X= -11

Step-by-step explanation:

Combine the two equations to equal a supplementary line

(X+91)=(x+111)=180

Solve for x by reversing the equation

(x)+(x)=(180-91)+(-111)

x=-22/2

x=-11

then check it

Solve for x and y please ASAP it is urgent, please give a logical explanation, will rate highly and award brainliest.

-7x+5y=-8
9x-8y=15

Answers

Answer is (-1,-3)
Step by step explanation:
Solving for x:
-7x+5y=-8
Multiply both side’s by 8
-56x+40y=-64

9x-8y=15
Multiply both sides by 5
45x-40y=75

Subtract
-56x+40y=-64
45x-40y=75
-11x=11
-11x/-11 = 11/-11
x=1

Substitute -1 for x to get y
-7(-1)+5y=-8
Multiply 7 and -1
7+5y=-8
Then subtract 7 from both sides
5y=-15
Then divide both sides by 5
Y=-3

Josh practices free throws during basketball practice on Monday and Tuesday. On Monday, he attempts 15 free throws and 6 basketballs went in the basket. Over both days, Josh wants at least 80% of his balls to go in the basket. If he makes every free throw on Tuesday, what is the minimum number of free throws required on Tuesday to reach his goal?

Answers

Answer:

he has to make 12 shots

Step-by-step explanation:

Josh will have to make a minimum of 12 shots to the basket to reach his goal on Tuesday. Basically, 12 shots are 80% of 15 shots he decides to take every Monday and Tuesday.

Baskets are said to be done when the basketball ends up passing through the basket in the opponent's side of the basketball field. However, Josh is practicing his free throws here.

Josh has set a goal to himself that at least 80% of his shots should be basket. Considering that he takes 15 throws on Monday the calculation of baskets will be done as below.

  [tex]\rm Josh's goal= \dfrac{80}{100} x 15[/tex]

So the Josh's required free throws on Tuesday will be,

 [tex]\rm Josh's\ goal = 12[/tex]

It can be concluded that Josh will have to make at least 12 of his 15 free throws into the basket on Tuesday to achieve his set goal of 80%.

Hence, Josh will have to make 12 free throws into the basket on Tuesday to be able to score at least 80% of his free throws as baskets.
