Evelina is shopping for back-to-school clothes. She bought 3 skirts, 2 pairs of
jeans, and 4 sweaters. Write and evaluate an expression to find out how much she
spent.

Answer:

y = -x - 5

Step-by-step explanation:

y = mx + b

slope = m = -1

y = -1x + b

y = -x + b

Plug in (-7, 2) for x and y, and solve for b.

2 = -(-7) + b

2 = 7 + b

b = -5

y = -x - 5

Answer:

its one i think  

Answer:

Here,  more than indicates adding, and products means result of multiplication

Thus,

6* 14+x

NOTE: These questions are to be made into an equation with using a variable. That is what i have done but if the questions states something abt the final result we get then we need to solve for x

Step-by-step explanation:

Since the the two angles are complementary, then

[tex](3x + 2) + (5x - 14) = 90[/tex]

or

[tex]8x - 12 = 90 \Rightarrow 8x = 102[/tex]

[tex]x = 12.75[/tex]

so

[tex]\angle{YXZ} = 5(12.75) - 14 = 49.75°[/tex]

Step-by-step explanation:

N = 0.733t + 8.398

N = 0.733(1971) + 8.398

N = 1,453.141

Step-by-step explanation:

Solution,

According to question,

N=0.733t + 8.398

When t= 1971, then

N=0.733×(1971) + 8.398

N=1453.141

Answer: 9x+−60

Step-by-step explanation:

You only attached the square. Edit the question to add it, and then I'll edit my answer.

Two step equations are equations which take 2 steps to solve. Let's create our equation now.

2p + 2 = 3

If you'd like, you can solve it to ensure it's correct.

2p + 2 = 3

Subtract 2 from both sides.

2p = 1

Divide both sides by 2

p = 0.5

Answer:

500

have a nice day!

Hey there!

4 = 4,000 = thousands

5 = 500 = hundreds

7 = 70 = tens

8 = 08 = ones

.

3 = 0.3 = tenths

6 = 0.06 = hundredths

4 = 0.004 = thousandths

Therefore, your ANSWER is: hundreds

Good luck on your assignment and enjoy your day!

Answer:

answer is 6.3

Step-by-step explanation:

there is no way to get 6.80 from 2.25*2.80 because its answer is 6.3

Answer:

A centimeter is smaller than an inch, so a given length will have more centimeters than inches. This alone shows you that the NUMBER of cm units will always be greater than the number of inches, for a given measurement.

Answer:X is greater than or equal to -1

Step-by-step explanation:

-4<7x-3-6x

-4<x-3

-4+3<x

-1<x

x>-1

Every greater than or less than sign should be equal to so they are all greater than or equal to or less than or equal to :)

Answer:

120

Step-by-step explanation:

12 and 40

Multiples of 12 = 12,24,36,48,60,72784,96,108,120..

Multiples of 40 = 40,80,120..

Common in both = 120

Answer:

120

Explanation:

The least common multiple (LCM) of two or more whole numbers is the smallest whole number that is divisible by each of those numbers. Basically, the LCM is the smallest number that all the numbers divide into evenly. So for 12 and 40, we get 120 since 120 ÷ 12 = 10, 120 ÷ 40 = 30

[tex]Hello[/tex] [tex]There![/tex]

The answer is...

[tex]y=-8x+15.[/tex]

HERE'S THE EXPLANATION!

Let's solve for y.

[tex]8x+y=15[/tex]

Step 1: Add -8x to both sides.

[tex]8x+y+-8x=15+-8x[/tex]

[tex]y=-8x+15[/tex]

THE ANSWER!

[tex]y=-8x+15[/tex]

Hopefully, this helps you!!

Answer:

not sure what is the question

Step-by-step explanation:

Answer:

Q1 = 5

Step-by-step explanation:

Q1 is the first quartile

Divide the data in half, that will get you Q2 or the second quartile

There are 13 data points so the middle is the 7th data point

2, 3, 5, 5, 6, 8,    8,       9, 10, 11, 11, 11, 12

Take the lower half of the data and divide it in half

There are 6 data points so the middle is between the 3rd and the 4th data point so we average them

2, 3, 5,    5, 6, 8,

(5+5)/2 = 10/2 = 5

The 1st quartile or Q1 = 5

Answer:

1 f(-5) = 3(-5)-1= – 15 – 1 = – 16

2. h(1) = 2(1)+3=2+3=5

g(2)= 3- 4(2)=3 – 8 = – 5

3h(1) ‐ g(2) = 3 (5) – (-5) = 15 +5= 20

I hope I helped you^_^

Answer:

number 1 =

Let  y=f(x)=3x−5

Clearly f(x) is one-one onto function so it is invertible.

y=3x−5 ⇒x =   y+5/3

∴f  −1 (x)=   y+5/3

number 2=

(g-h)= 4x+3-x3-2x3

(g-h)=4(-1)+3-(-1)2-2(-x)2

(g-h)=-4+3-(-1)-2(1)

(g-h)=-4+3+1 -2

(g-h) =  2
