Step-by-step explanation:
Jenny is 9 years younger than Sammie. Five years ago, Sammie was four times older than Jenny. How old is each now?
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.

If 4x + b = 12, then x is equal to:
Answer:
4x + 12 = 24
Subtract 12 to both sides
4x + 12 - 12 = 24 - 12
4x = 12
Divide 4 to both sides
4x ÷ 4 = 12 ÷ 4
x = 3
Step-by-step explanation:
A 12-sided die is rolled. The set of equally likely outcomes is {1,2,3,4,5,6,7,8,9,10,11,12). Find the probability of rolling a number greater than 12.
The probability of rolling a number greater than 12 is
(Type an integer or a simplified fraction.)
Answer:
[tex]P(x>12) = 0[/tex]
Step-by-step explanation:
Given
[tex]x = \{1,2,3,4,5,6,7,8,9,10,11,12\}[/tex] --- outcomes
[tex]n(x) = 12[/tex] -- sample size
Required
[tex]P(x > 12)[/tex]
This is calculated as:
[tex]P(x > 12) = \frac{n(x > 12)}{n(x)}[/tex]
[tex]n(x>12) = 0[/tex] because none of the outcomes is greater than 12:
So:
[tex]P(x > 12) =\frac{0}{12}[/tex]
[tex]P(x>12) = 0[/tex]

Solve the system using elimination. 4y+x= -17 -2y+2x =16
Answer:
(3, -5)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightDistributive Property
Equality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityAlgebra I
Coordinates (x, y)Solving systems of equations using substitution/eliminationStep-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 = 32Step 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 = 3Step 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 = -5Answer:
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)
x=3
Answer:
x=3 and y=−5

which one is greater/less than?
-25% or 25%
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%

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?
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
