3(2c + 5) = 39
What is the answer ?
Answers
Answer:
c=1
Step-by-step explanation:
Simplifying
3 + 2c = 5
Solving
3 + 2c = 5
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2c = 5 + -3
Combine like terms: 3 + -3 = 0
0 + 2c = 5 + -3
2c = 5 + -3
Combine like terms: 5 + -3 = 2
2c = 2
Divide each side by '2'.
c = 1
Simplifying

A cylinder has a base diameter of 20in and a height of 17in. What is its volume in cubic in, to the nearest tenths place?
Answers
Step-by-step explanation:
(3.1415 * 10^2) area of base
(17) height
volume = area of base * height
volume = 3.1415 * 10^2 * 17
The volume of the cylinder is 533.8 cubic inches to the nearest tenths place
Volume of Cylinder based problem:What information do we have?
Diameter of cylinder = 20 inch
Height of cylinder = 17 inch
Volume of Cylinder = πr²h
Volume of Cylinder = (3.14)(20/2)²(17)
Volume of Cylinder = (3.14)(10)(17)

When interpreting graphs from real-world situations, what can the slope tell you about the situation?
Answers
When interpreting graphs of real world situations, the slope of each part tell you the average rate of change (increase or decrease) of the dependent variable with respect to the independent variable. This is, how much the dependent variable increased (or decrease) per each unit the independent varaible increased, in average.
slope = change in independent variable / change in dependent variable
slope = Δy / Δx

Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount.
Together the coaches spend $40. How much does each cone cost?
( write an equation to model the situation. Then solve for x)
Answers
Answer:
x=16
Step-by-step explanation:
1 soccer ball =$12
2 makes $24.
24+16=40
so both coaches spend 8 bucks for 4 cones
Each cone costs $2, and the cost is calculated as follows: 8x = 40 - 2 *p, where p is equal to the cost of a football.
What is a Linear equation?A linear equation is an algebraic equation of the form ax + by +c, is and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given that, Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount. Together the coaches spend $40.
Let x be the number price of the cone.
Thus each coach spends = 4x +12
Thus, in total, they spend = 40
4x +12 + 4x +12 = 40
8x = 40 -24
8x = 16
x = 2
Therefore, Each cone costs $2 and the equation for calculating the price of the cone is: 8x = 40 - 2 * the price of a football.

O 4 red marbles and 6 blue marbles
O 4 red marbles and 5 blue marbles
O 6 red marbles and 8 blue marbles
Answers
Answer:
4 red marbles and 6 blue marbles is the correct answwer
Step-by-step explanation:
Answer:
A.) 4 red marbles and 6 blue marbles
Step-by-step explanation:
If you times 2 x 2 then you will get 4
If you times 3 x 2 then you will get 6
And since the ratio is red : blue
2 : 3 is equivalent to 4 : 6
Just like [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.

What is the y intercept of y=6x+3
Answers
Answer:
y = 6 x − 3
Step-by-step explanation:
The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept.
y = m x + b
Using the slope-intercept form, the y-intercept is − 3 .
b = − 3
Answer:
-3
Explanation:
I remember the formula to be y=mx+b, and mx representing the slope times x. Therefore, b would equal the y-intercept, or in this case 3. Using slope intercept form, you get -3.
