14. Question wise,

In ΔRST,

∠R=2x+5

∠S=x+1

∠T=7x-16

we know,

∠R+∠S+∠T=180 [sum of 3 angles of a triangle is 180°]

2x+5+x+1+7x-16=180

10x-10=180

10(x-1)=180

x-1=18

x=19

so,

∠R=(2×19)+5=43

∠S=19+1=20

∠T=(7×19)-16=117

15. Question wise,

In ΔABC,

∠A=∠C-13

∠B=4∠C-11

we know,

∠A+∠B+∠C=180 [,,]

∠C-13+4∠C-11+∠C=180

6∠C-24=180

6∠C=180+24

∠C=204÷6=34

so,

∠A=34-13=21

∠B=(4×34)-11=125

16. Question wise,

In ΔJKL

∠K=∠J+9

∠L=2∠J-21

we know,

∠J+∠K+∠L=180

∠J+∠J+9+2∠J-21=180

4∠J-12=180

4∠J=180+12

∠J=192÷4=48

so,

∠K=48+9=57

∠L=(2×48)-21=75

Answer:

-2

Step-by-step explanation:

14/7 = 2

So,

-14/7 = -2

Check:

-2 x 7 = -14

Answer:

-2

Step-by-step explanation:

because 7 can go into 14 2 times and since the 14 is negative the answer is negative

Answer: -4c+12

all real numbers

Step-by-step explanation:

6) 28-(3c+4) =2 (c+6)+c

When there is a - in front of an expression in parentheses , change the sign of each term of the expression.

28-3c-4=2(c+6)+c

Distribute 2 through the parentheses

28-3c-4=2c+12+c

Now we do the same thing only different way

2(c+6)

Multiply each term in the parentheses by 2

2c+2×6

Multiply the numbers

2c+12

_____________

28-3c-4=2c+12+c

subtract the numbers

24-3c=2c+12+c

Collect like terms

24-3c=3c+12

It's the same thing only different way ok

2c+c

If a term doesn't have a coefficient , it is considered that the coefficient is 1.

2c+1c

Collect like terms by adding their coefficients

(2+1)c

Add the numbers

3c

________

24-3c=3c+12

Move variable to the left hand side and change its sign

24-3c-3c=12

Move constant to the right  by adding its opposite to both sides

-3c-3c+24-24=12-24

eliminate the opposites

-3c-3c=12-24

Collect like terms

-6c=12-24

Calculate the difference

-6c=-12

so the same thing only different way ok

12-24

Keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger.

-(24-12)

Subtract the numbers

-12

__________

-6c=-12

divide both sides of the equation by -6

-6c÷(-6)=-12÷(-6)

Any expression divided by itself equals 1

c=-12÷(-6)

Dividing two negatives equals a positive

(-)÷(-)=(+)

c=12÷6

Calculate the quotient

c=2

Answer:

Your small pepperoni pizza would need to bake for 19 minutes

Step-by-step explanation:

Since the small pepperoni pizza has to bake 7 minutes longer that a small plain pizza which takes 12 minutes all you have to do is add 12 + 7

Answer:

p ≥ 5

Scott will buy at least 5 kilograms of candy.

Step-by-step explanation:

Inequalities

The candy Scott buys cost $7 per kilogram.

Let's set p=number of kilograms of candy Scott will buy.

The money spent to buy p kilograms of candy is 7p dollars.

The condition states he will spend at least $35 on candies, thus the following inequality is formed:

7p ≥ 35

Dividing by 7:

p ≥ 35/7

Operating:

p ≥ 5

Scott will buy at least 5 kilograms of candy.

Answer: 8

Step-by-step explanation:

Answer:

If i'm not wrong 8 minutes.

Step-by-step explanation:

If you add all the meters together its adds up to 1600. It says you run 200 meters per minute so it will take 8 minutes to run around the track 4 times.

Answer:

A. solid to a liquid

Step-by-step explanation:

When you melt something it is always going to start off as a solid then turns into a liquid.

You can never melt something to make it a solid again like you cant melt water to make it ice, you can melt ice to make it water.

Hence, why the answer is A. solid to a liquid

Answer: f(x)

Step-by-step explanation:

Answer: 2u+4 <8= u<2

2u+4<8

Step 1: Subtract 4 from both sides.

2u+4−4<8−4

2u<4

Step 2: Divide both sides by 2.

2u/2<4/2

u<2

4u-53 15

=4u−795

Step-by-step explanation:

Answer:

x = 30

Step-by-step explanation:

First you would add the like terms, which are 2x and 4x, which gives you 6x. Now the equation would read 6x + 6 = 180

You need to get rid of the six, and since what you do to one side of the equation must be done to the other, you need to subtract 6 from both sides to cancel out the 6 on the left side of the equation. The equation is now 6x = 180. Now you need to divide both sides by 6, which gives you x = 30.

Answer: x=29

2x+6+4x=180

combine like terms

2x+6+4x=180

6x+6=180

subtract 6 from both sides

6x+6-6=180-6

simplify

6x=174

divide both sides of the equasion by the same term

6x=174

6x=176

6   6

simplify again

x=29

Answer:

x=26

Step-by-step explanation:

1. (3-4) + x = 25

2. 3-4=-1

3. -1+x=25

4. -1+26=25

Let X represent the number we don't know, so X in this equation would equal 26 because -1+26=25 and 25 is the number we are trying to equal. I hope this helped. Let me know if I need to explain something else you don't understand in this equation, hope this helped! xx

Answer:

1st picture (tri) = 16y+8

2nd picture (tri) = 12x-9

3rd picture (sq) = 21x+35

Step-by-step explanation:

Triangle area = (Base x Height) divided by 2

#1.)  16(2y+1) = 32y + 16            (32y+16)/2 = 16y+8

Step-by-step explanation:

Answer:

[tex]P=150+150t[/tex]

Step-by-step explanation:

Let P denotes the total cost and t denotes the time.

Total cost for 2 hours = $300

So,

Cost for 1 hour = [tex]\frac{300}{2} =\$150[/tex]

Also,

Fixed fee to use the studio = $150

The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio.

Therefore,

Total cost = Fixed fee to use the studio + Hourly fee for each hour in the studio

[tex]P=150+150t[/tex]
