ANSWER:

(x,y) = (5,-1)

Answer:

(5, -1)

Step-by-step explanation:

Solve the system of equations by elimination.

4x + 3y = 17

3x + 2y = 13

Multiply the top equation by -3 and the bottom equation by 4:

-12x - 9y = -51

12x + 8y = 52

Add these together:

-y = 1

y = -1

Plug in -1 as y into one of the equations, and solve for x:

4x + 3y = 17

4x + 3(-1) = 17

4x - 3 = 17

4x = 20

x = 5

So, the solution is (5, -1)

Answer:

❘-40 - 140❘

Step-by-step explanation:

Given that,

Franky’s SAT score was 140 points above the average score.

Francesca’s SAT score was 40 points below the average score.

We need to find the expression that represents the difference in their scores. It can be calculated as follows :

d = ❘-40 - 140❘

= -180

Hence, the correct option is (A) "❘-40 - 140❘".

Answer: Nolan worked 4 hours, and Mia worked 8 hours

Step-by-step explanation:

Step-by-step explanation:

Let x represent the number of hours Nolan worked.

Let y represent the number of hours Mia worked.

Mia worked twice as many hours as Nolan. This means that

y = 2x

Nolan can iron 25 shirts per hour, and Mia can iron 35 shirts per hour. Together, Nolan and Mia ironed 380 shirts between them. This means that

25x + 35y = 380 - - - - - - - - - - - - - -1

Substituting y = 2x into equation 1, it becomes

25x + 35 × 2x = 380

25x + 70x = 380

95x = 380

x = 380/95

x = 4

y = 2x = 2 × 4

y = 8

Answer:

1). No, symbol won't be reversed

2.) No, symbol won't be reversed

3.) yes, symbol will be reversed

4.) No, symbol won't be reversed

Step-by-step explanation:

1.)

-10.5 < 3a

-10.5 /3 < 3a /3

-3.5 < 3 (No)

2.)

b/6 ≤ 7

Multiply both sides by 6

b/6 * 6 ≤ 7 * 6

b ≤ 42 (No)

3.)

-4.5c > 9

Dibide both sides by - 4.5

-4.5c / - 4.5 > 9/-4.5

c < 2 (yes)

4.)

–21/5 ≤ –5/2d

Multiply both sides by 2/5

-21/5 * 2/5 ≤ - 5/2d * 2/5

-21/2 ≤ - d

21/2 ≤ d (No)

Answer:

-13

Step-by-step explanation:

Well, they do most of the work for you all you have to figure out is what is "1/5(-65)". To do this you have to turn 1/5 into a decimal so 1 divided by 5 which equals 0.2 then multiply that by -65. That will give you your simplified answer of -13.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

each of the 6 number has a 1/6 chance of being rolled

 1       2       3      4      5       6

1/6     1/6    1/6    1/6    1/6    1/6

Every time the cube is rolled  there is a 6/6 chance of any number comes up

1/6  +   1/6  +  1/6 +   1/6 +   1/6  +  1/6   = 6/6     or  1  

What is the probability of NOT rolling a 2? Any other number

 1        2       3        4        5         6

1/6  +   0  +  1/6 +   1/6  +  1/6 +   1/6   =   5/6    or    0.8333

Answer:

-2/2

Step-by-step explanation:

I think the slope is -2/2 I hope I got this right, sorry if I got it wrong. Anyway, you solve this by plotting your two points, then doing rise over run (down 2 and over to the right).

Your welcome :D.

Answer:

Slope: -1

Step-by-step explanation:

( 3, -6) and (5, -8)

m= (y2-y1)/(x2-x1)

m = ( -8 + 6)/ (5-3)

m = (-2)/2

m = -1

Answer:

Jamila need's 375g of butter

Step-by-step explanation:

12 biscuits , but she wants to make 36,

12x3 = 36 so times to rest of the ingredients by 3

250x3=750g Oats

125x3=375g Butter

100x3=300g Sugar

2x3= 6 tablespoons of syrup

Jamila needs 375 g of butter to make 36 biscuits.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If the recipe makes 12 biscuits and Jamila wants to make 36 biscuits, she needs to triple the recipe.

To triple the amount of butter, we can multiply 125 g by 3:

125 g x 3 = 375 g

Therefore,

Jamila needs 375 g of butter to make 36 biscuits.

Answer:

y = -x - 2

Step-by-step explanation:

y = x +  2        {Compare with y = mx + c}

Slope = m1 = 1

Slope of the line S = m2 = -1/m1 = -1/1 = -1

(-6 , 4)

y -y1 = m (x -x1)

y - 4 = (-1)(x - [-6] )

y -4 = (-1)(x + 6)

y -4 = (-1)*x + (-1) *6

y - 4 = -x - 6

     y = -x - 6 + 4

    y = -x - 2

Answer:

7.5 laps

Step-by-step explanation:

First, you wanna figure out how many yards is in one lap

to do this, you would multiply 100 and 4 (four because there's four equal sides  in one lap)

100 x 4 = 400

You know their speed is 5 yards per second, so you wanna find out how many seconds they will be running

to do this, you multiply 60 (sixty because there's sixty seconds in one minute) and 10 (ten because that's the given amount of minutes)

60 x 10 = 600 seconds

now to found out how much they will run in 10 minutes you will multiply 600 by 5

600 x 5 = 3000 yards

now to find how many laps this is, you can divide 3000 yards by 400 yards

3000 ÷ 400 = 7.5 laps
