Answer:
21
Step-by-step explanation:
You must find a number that will divide into the total of the girls and boys and come up with an even number. By looking at the numbers, you can see that both 56 and 91 will divide evenly by 7. The common denominator for both calculations is 7.
56/7=8 girls
91/7= 13 boys
Add 8 girls and 13 boys and you will have 21 in each group. That way, all groups are equally boys and girls.
8+13=21

Joe is 14 years older than his cousin Tom.
Cousin Rob is 3 times as old as Tom. The sum of all
three of their ages is 64. Find each of their ages.
x = Tom's age
x + 14= Joe's age
3x = Rob's age
x + (x + 14) + 3x = 64
Let's combine like terms
5x + 14 = 64
Subtract 14 from both sides
5x = 50
Divide each side by 5
x = 10
Tom is 10 years old.
Joe's age = 10 + 14 = 24 years old
Rob's age = 3(10) = 30 years old

My son drinks 3 cups of milk a day. There are 8 ounces in a
cup. How many ounces would he have drunk after 10
weeks? 8 ounces = 1 cup
Answer:
1680
Step-by-step explanation:
3 Cups/Day
3*8=24 Oz/Day
24*7=168 Oz/Week
168*10=1680 Oz in 10 Weeks
The solution is : 1680 ounces he will drink after 10 weeks.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
Here, we have,
given that,
My son drinks 3 cups of milk a day. There are 8 ounces in a cup.
so, we have,
My son drinks milk:
3 Cups/Day
we know, 8 ounces = 1 cup
so, we get,
3*8=24 ounces/Day
now, we have,
7 day = 1 week
we get,
24*7=168 ounces/Week
we have,
168*10=1680 ounces in 10 Weeks.
Hence, The solution is : 1680 ounces he will drink after 10 weeks.

Solve for p
P/x + z = y
Step-by-step explanation:
p/x + z = y
p/x = y-z/1
p = x (y-z)
I need help with this one.
Answer:
y = 3x + 5
Step-by-step explanation:
The equation in slope- intercept form is
y = mx + c
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (2, 11) ← 2 ordered pairs from the table
m = [tex]\frac{11+1}{2+2}[/tex] = [tex]\frac{12}{4}[/tex] = 3, thus
y = 3x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (2, 11 ), then
11 = 6 + c ⇒ c = 11 - 6 = 5
y = 3x + 5 ← equation of linear function

I played 4 video games and had an average score of 12,000 points
per game. The average score of the first 3 games was 11,000 points
per game. How many points did I score in the 4th game?
Answer:
15,000
Step-by-step explanation:
The first three games leave you with at total that is 3000 below the average. So, the last game has a score that is 3000 above average:
12000 +3000 = 15000 points scored in 4th game
__
Check
(11000 +11000 +11000 +15000)/4 = 48000/4 = 12000
The average of anything is calculated by adding up all the values and dividing by the number of values.
The Average = 12,000
the # of values = 4
x = score of the 4th game
(11,000 + 11,000 + 11,000 + x) / 4 = 12,000
First, let's multiply both sides by 4
11,000 + 11,000 + 11,000 + x = 48,000
Let's simplify the left side
33,000 + x = 48,000
Subtract 33,000 from both sides
x = 15,000
You scored 15,000 points in the 4th game

O B. (x+3)(x + 6)(x - 1)
O c. 3(x - 1)(x+3)(x+2)
D. (x-3)(x + 3)(x - 2)
Answer:
C
Step-by-step explanation:
Given
3x³ + 12x² + 3x - 18
The sum of the coefficients = 3 + 12 + 3 - 18 = 0
Thus x = 1 is a root and (x - 1) is a factor
Divide 3x³ + 12x² + 3x - 18 by (x - 1) using Synthetic division
1 | 3 12 3 - 18
↓ 3 15 18
-----------------------------
3 15 18 0 ← remainder
Quotient = 3x² + 15x + 18 = 3(x² + 5x + 6)
Thus
3x³ + 12x² + 3x - 18 = 3(x - 1)(x² + 5x + 6) = 3(x - 1(x + 3)(x + 2) → C
4r+8+5=-15-3r ANSWER NUMBER FORM NO WORDS AT ALL
Answer:
r = -4
Step-by-step explanation:
Step 1: Write out equation
4r + 8 + 5 = -15 - 3r
Step 2: Combine like terms
4r + 13 = -15 - 3r
Step 3: Add 3r to both sides
7r + 13 = -15
Step 4: Subtract 13 on both sides
7r = -28
Step 5: Divide both sides by 7
r = -4
Answer: r=-4
Step-by-step explanation:
4r+13=-15-3r
7r+13=-15
7r= -28

All of the angles in a triangle equal 180 degrees.
There is a 90 degree angle, and two unknown angles.
Your equation would be 90 + 2x - 2 + x + 5 = 180.
Combine like terms: 3x + 87 = 180.
Subtract 87: 3x = 93.
Divide 93 by 3 to cancel out x, and you get x = 31.

Find the area of a triangle with a base of 27ft and a height of 14ft
Hi there! :)
Answer:
[tex]\huge\boxed{A = 189 ft^{2}}[/tex]
Formula for the area of a triangle:
A = 1/2(b · h) Where:
b = base, h = height
Substitute in the given values for the base and height:
A = 1/2(27 · 14)
A = 1/2(378)
A = 189 ft².
Determine whether each equation has no solution, one solution, or infinitely many solutions.
Drag each equation to the correct location on the table.
Answer:
Step-by-step explanation:
No solution - 2y – 3 = 5 + 2(y – 1), one solution - (1/5)f – 2/3 = – (1/5)f + 2/3, 4a – 3 + 2a = 7a – 2, infinitely many solution - [-3(n + 4) + n = -2(n + 6)], -1.7v + 2.8 = 1.4v – 3.1v + 2.8.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
If the exponent of the variable is one, then one solution.
If both sides are zero, then no solution.
And if the variable is eliminated, then the infinitely many solutions.
-1.7v + 2.8 = 1.4v – 3.1v + 2.8, it has infinitely many solutions.
4a – 3 + 2a = 7a – 2
a = -1, it has one solution.
(1/5)f – 2/3 = – (1/5)f + 2/3
f = 5/3, it has one solution.
2y – 3 = 5 + 2(y – 1)
0 = 0, it has no solution.
-3(n + 4) + n = -2(n + 6), it has infinitely many solutions.

= 18/72
18/18=1
72/18=4
= D.) 1/4
Answer:
D. 1/4
Step-by-step explanation:
First, we will multiply the numerator 6 × 3 = 18. Then, we'll multiply the denominators, 9 × 8 = 72. Then, divide 18 ÷ 18 = 1 and 72 ÷ 18 = 4. So there we go. the numerator is 1 and the denominator is 4. So the answer is 1/4 which is a proper fraction :) (mark this answer brainliest plz )

In domain
Not in domain
Answer:
Only -2 is in the domain because if you substitute -2 in for x, you would get a positive answer. The others would not work because you would get a negative number inside the square root, and you can't square root a negative number unless you are allowed to use imaginary numbers.
