Algebra I

Coordinates (x, y)Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

4y + x = -17

-2y + 2x = 16

Step 2: Rewrite Systems

-2y + 2x = 16

[Multiplication Property of Equality] Multiply 2 to both sides: 2(-2y + 2x) = 32[Distributive Property] Distribute 2: -4y + 4x = 32

Step 3: Redefine Systems

4y + x = -17

-4y + 4x = 32

Step 4: Solve for x

Elimination

Combine equations: 5x = 15[Division Property of Equality] Divide 5 on both sides: x = 3

Step 5: Solve for y

Substitute in x [Original Equation]: 4y + 3 = -17[Subtraction Property of Equality] Subtract 3 on both sides: 4y = -20[Division Property of Equality] Divide 4 on both sides: y = -5

Answer:

Step-by-step explanation:

Let's solve your system by elimination.

4y+x=−17;−2y+2x=16

Multiply the first equation by -2,and multiply the second equation by 1.

−2(4y+x=−17)

1(−2y+2x=16)

Becomes:

−2x−8y=34

2x−2y=16

Add these equations to eliminate x:

−10y=50

Then solve −10y= 50 for y:

−10y=50

−10y /−10 = 50/ −10 (Divide both sides by -10)

y = −5

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

4y + x = −17

Substitute −5 for y in 4y+x=−17:

(4)(−5)+x=−17

x−20=−17(Simplify both sides of the equation)

x−20+20=−17+20(Add 20 to both sides)

Jenny is 9 years younger than Sammie. Five years ago, Sammie was four times older than Jenny. How old is each now?

Answers

Answer:

Jenny's is 8 now and Sammie is 17.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

Jenny's age is x.

Sammie's age is y.

Jenny is 9 years younger than Sammie.

This means that:

[tex]x = y - 9[/tex]

Five years ago, Sammie was four times older than Jenny.

This means that:

[tex]y - 5 = 4(x - 5)[/tex]

Since [tex]x = y - 9[/tex]

[tex]y - 5 = 4(y - 9 - 5)[/tex]

[tex]y - 5 = 4(y - 14)[/tex]

[tex]y - 5 = 4y - 56[/tex]

[tex]3y = 51[/tex]

[tex]y = \frac{51}{3}[/tex]

[tex]y = 17[/tex]

[tex]x = y - 9 = 17 - 9 = 8[/tex]

Jenny's is 8 now and Sammie is 17.

Sally is making 15 individual blueberry cheesecakes. How many pounds of blueberries will be in each cheesecake if 5 1/4 pounds of blueberries are divided equally among them?

Answers

Answer:

0.35 pounds in each cheesecake

Step-by-step explanation:

Number of individual blueberry cheesecakes = 15

Pounds of blueberries = 5 1/4 pounds

How many pounds of blueberries will be in each cheesecake if 5 1/4 pounds of blueberries are divided equally among them?

= 5 1/4 ÷ 15

= 21/4 ÷ 15

= 21/4 × 1/15

= (21*1)/(4*15)

= 21/60 pounds

Equivalent to 0.35 pounds in each cheesecake

which one is greater/less than?

-25% or 25%

Answers

Answer:

25% is greater then -25.

Step-by-step explanation:

-25 is in the negiatives, and is to the left of 0. Anything to the left of 0 will be less then anything on the right of 0. :D

-25% will always be less than 25% because a negative number, being less than 0, will always be less than a positive number, being greater than 0.

Thus, -25% is less than 25% or 25% is greater than -25%
