A clothing store is having a sale in which everything is 10% off. A shirt's original price is $27. A customer uses a coupon for $5 off after the sale price. How much did the customer save?

Answer:

x=11

Step-by-step explanation:

complimentary means the two angles add to 90. Since we already know one angle equals 68, subtract 68 from 90= 22. 2x=22. divide 22 by 2 to isolate the variable. Boom, the answer is x=11

Answer:

x < 5/9

Step-by-step explanation:

Answer: x < 5/9

Step-by-step explanation:

36x < 20 (divide both sides by 36)

x < 20/36 (simplify the fraction)

x < 5/9

Answer: p>−4

Step-by-step explanation:

Let's solve your inequality step-by-step.

Step 1: Simplify both sides of the inequality.

−7p−2<26

Step 2: Add 2 to both sides.

−7p−2+2<26+2

−7p<28

Step 3: Divide both sides by -7.

$52.50

Step-by-step explanation:

(2[7.25] + 2[24]) - 10

(14.50 + 48) - 10

62.50 - 10

= 52.50

Answer:

I think it is the second one because -4 is the least

Step-by-step explanation:

Answer: It’s the first option.

Step-by-step explanation:

/-4/ the bars on either side of the -4 means absolute value. The absolute value of any number is the number itself, regardless of positive or negative. /-4/ is 4.

15/3 is 5. (3 goes into 15 five times)

16/3 is 5 1/3. (3 goes into 16 five times with 1 leftover. Place the leftover 1 back on top of the denominator)

Multiples of a number are the numbers that a number can be divided by without any remainder.

The buses X and Y will leave at the same time by 8:40 am

To calculate when buses X and Y will leave at the time, we would have to find the Lowest Common Multiple of 20 and 25 minutes.

Find and list multiple until the first common multiple is found. This is the lowest common multiple.

Multiples of 20:

20, 40, 60, 80, 100, 120, 140

Multiples of 25:

25, 50, 75, 100, 125, 150

Therefore,

LCM(20, 25) = 100

The LCM is 100 minutes

Converting 100 minutes

60 minutes = 1 hour

100 minutes = ?

Cross Multiply

100 minutes x 1 hour / 60 minutes

= 1 2/3 hours.

This can be rewritten as :

= 1 hr 40 minutes

Adding this to 7am

7 am + 1 hr 40 minutes = 8 : 40am

Therefore, the buses X and Y will leave at the same time by 8:40 am

Answer:

y = -2/3x + 6

Step-by-step explanation:

Kind of hard to explain but...

From 0,0 go up 6, that is where the + 6 comes from in the answer

The -2/3 is because if you go down 2 (aka -2) and right 3 (aka 3) from point 0,6 you land on point 4,4

Answer:

28:20

Step-by-step explanation:

you just multiply 5 by 4 because 20 divided by 4 is 5 and then multiply 7 by 4

Answer:

Let total students be ‘X’

No of girls = (X-20)

Girls/Boys=7/5=(X-20)/20

7(20) =5(X-20)

140=5X-100

5X=240

X = 240/5

X =48

So, Total Students are 48

No of girls = (X-20) = 48-20 = 28

Step-by-step explanation:

Answer:

See explanations below

Step-by-step explanation:

Slope intercept form of the equation is expressed as y = mx+b

m is the slope

b is the intercept

Given the coordinates (4, -11/3) and (1/2, -29/6)

Slope m = -29/6-(-11/3)÷(1/2-4)

m = (-29/6+11/3)÷(-7/2)

m = -29+22/6÷(-7/2)

m = -7/6÷(-7/2)

m = -7/6×2/-7

m = 2/6

m = 1/3

Get the intercept b

Substitute m= 1/3 and (4, -11/3) into y = MX+b

-11/3 = 1/3(4)+b

-11/3 = 4/3+b

b= -11/3-4/3

b= -15/3

b =-5

Get the required equation

y = 1/3 x -5 (slope-intercept form)

Point slope form of the equation is expressed as y-y0 = m(x-x0)

Substituting m = 1/3 and the point (4,-11/3)

x0 = 4

y0 = -11/3

y - (-11/3) = 1/3(x-4)

y+11/3 = 1/3(x-4) (point-slope form)

For standard format

Recall that y = 1/3x - 5

Multiply through by 3

3y = 1/3x(3)-5(3)

3y = x-15

3y-x = -15(standard form)

Answer:

if f(g(x)) = g(f(x)), then x is equal to zero.

Step-by-step explanation:

given:

f(x) = 2x²

g(x) = x + 1

then:

f(g(x)) = 2(x + 1)²

g(f(x) = 2x² + 1

so if:

f(g(x)) = g(f(x))

then:

2(x + 1)² = 2x² + 1

2(x² + 2x + 1) = 2x² + 1

2x² + 2x + 1 = 2x² + 1

2x = 0

x = 0
