In a basketball tournament, Team A scored 5 fewer than twice as many points as Team B. Team C scored 80 more points than Team B. The combined score for all three teams was 983 points. Write an equation to represent this scenario using the variable b to represent Team B’s total points.
Translate the scenario.
Team A =
Team B =
Team C =
The equation representing this scenario is
.
Answer:
Team A = 449
Team B = 227
Team C = 307
Equation is
(2b-5) + b + (b+80) = 983
simplyfying
4b+75 = 983
Step-by-step explanation:
Take 4b+75 = 983
b = (983 - 75)/4 = 227
now
Team A = 5 less than twice as many as team B = 2b - 5 = 2 *227-5 = 454-5= = 449
Team B = b = 227
Team C = 80 more than team B = b+80 = 227+80 = 307
or you can just subtract 983 - (Team A +Team B)
Answer:
Team A = 449
Team B = 227
Team C = 307
Equation is
(2b-5) + b + (b+80) = 983
simplyfying
4b+75 = 983

Solve the equation: -68 = 5y - 3
Answer:
-13
Step-by-step explanation:
-68 = 5y-3 First you move the -3 by adding 3 to both sides to get -65 =5y
Then you divide 5 by both sides to get y=-13
Answer:
y = -13
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-68 = 5y - 3
Step 2: Solve for y
Add 3 to both sides: -65 = 5yDivide both sides by 5: -13 = yRewrite: y = -13Step 3: Check
Plug in y to verify it's a solution.
Substitute: -68 = 5(-13) - 3Multiply: -68 = -65 - 3Subtract: -68 = -68And we have our final answer!
Each marble bag sold by Mary's Marble Company contains 5 blue marbles for every 4 purple
marbles. If a bag has 35 blue marbles, how many purple marbles does it contain?
Answer:
The total no. of purple marbles will be:
[tex] \boxed{ \underline{ \rm{28}}}[/tex]
Step-by-step explanation:
It is given that for every 5 blue marbles, we have 4 purple marbles. And similarly we have to find for the no. of purple marbles for 35 blue marbles.
First, Let's divide these 35 blue marbles in groups of 5. We will get:
➝ 35 ÷ 5 = 7 groups
For each group of 5 marbles, there are 4 purple marbles. So for 7 groups, No. of purple marbles will be:
➝ 4 × 7 = 28 purple marbles.
And we are done! :D

Which of the following is the slope of the line passing through the points A(-6, 10) and B(-2, 7)
Answer:
[tex]m=\frac{-3}{4}[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASAlgebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define Points
A (-6, 10)
B (-2, 7)
Step 2: Find slope m
Substitute: [tex]m=\frac{7-10}{-2+6}[/tex]Subtract/Add: [tex]m=\frac{-3}{4}[/tex]And we have our final answer!
Answer:
[tex]-\frac{3}{4}[/tex]
Step-by-step explanation:
To find the slope of the line, we use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when we are given the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].
When we plug the points A(-6,10) and B(-2,7) into the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], we get the equation [tex]\frac{7-10}{-2-(-6)}[/tex].
[tex]\frac{7-10}{-2-(-6)}\\= \frac{-3}{4}[/tex]
Therefore, the slope of the line is [tex]-\frac{3}{4}[/tex].

Use fives fact to help you solve 7 x 6. Show your work using
Using the "fives fact" (5 x 6 = 30) as a starting point, we added one more group of 6 to reach the final result of 36.
To use the "fives fact" to solve 7 x 6, we can break it down into simpler calculations using the fact that 5 x 6 = 30.
Here's the step-by-step calculation:
1. Start with the "fives fact": 5 x 6 = 30.
2. Since we need to find 7 x 6, we can add another 6 to the result of 5 x 6:
30 + 6 = 36
Therefore, 7 x 6 equals 36.

"X is the number of red marbles that Tonya has in her hand after she selects four marbles from a bag containing four red marbles and two green ones and then notes how many there are of each color."
Answer:
Explained below.
Step-by-step explanation:
There are four red marbles (R) and two green marbles (G) in the bag.
The random variable X is defined as the number of red marbles that Tonya has in her hand after she selects four marbles from the bag.
The probability of selecting a red marble is:
[tex]P(X)=\frac{4}{6}=0.667[/tex]
The sample space of X can be defined as follows:
Outcomes: {(RGGG), (RRGG), (RRRG), (RRRR), (RRGR), (RGRR), (GRRR), (RGRG), (GRRG), (RGGR), (GRGR), (GRGG), (GGRG), (GGGR), (GGGG)}
So, the sample space of X is:
S = {0, 1, 2, 3 and 4}

Explain why the exponent in 3.5 x 10 6 is 6 there are only 5 zeros in 3500000
Step-by-step explanation:
The given number is 3.5×10⁶. It is written in scientific form. We can first write it into standard form. There is exponent of 10 is 6.
3.5×10⁶ = 3.5×1000000
We can write 3.5 as 35/10
So,
3.5×10⁶ = (35/10)×1000000
= 3500000
One of the zero of 1000000 is divided by 10 at the denominator. Hence, the exponent in 3.5×10⁶ is 6 while there are 5 zeros in 3500000.

Laura is saving money to buy a bike. She has $52 and is going to save an additional $8 each week. The bike costs $164. In how many
weeks will she have enough money to buy the bike?
Answer:
I would say 14 weeks.
Step-by-step explanation:
I solved it by subtracting what she already has from the price of the bike. $164-52= 112. Then I divided that by 8 cause she saving $8 a week and you get 14. So in 14 weeks she'll have enough money to buy the bike.
