Answer:
The answer is A
Step-by-step explanation:
The equation has only one solution will be 2a + 7 = a + 10. Then the correct option is A.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
Let's check all the options, then we have
A. 2a + 7 = a + 10, simplify the equation, then we have
2a + 7 = a + 10
a = 3
B. a + 6 = 6 + a, the equation has infinite solutions.
C. 4a + 4 = 4a + 9, the equation has no solution.
D. 3x – 3 = 3(x – 1), the equation has infinite solutions.
The equation has only one solution will be 2a + 7 = a + 10. Then the correct option is A.

Step-by-step explanation:

Slope (m) = ΔYΔX= -4
1= -4
θ = arctan( ΔY ) + 360°
ΔX= 284.03624346793°
ΔX = 2 – 0 = 2
ΔY = 0 – 8 = -8
Distance (d) = √ΔX2 + ΔY2 = √68 = 8.2462112512353
Equation of the line:
y = -4x + 8
When x=0, y = 8
When y=0, x = 2
PLEASEEEEE HELPPPP MEEEE!!!! There are 5 friends who decide to split an 88- ounce bag of popcorn. If they split it evenly, how many ounces of popcorn will each friend get?
Solution:
Number Model:
Explain what you did with the remainder and why.
Answer:
17.6 ounces (U.S.) and or 2.2 cups (U.S.)
Step-by-step explanation:
88 ounces divided by 5 equals 17.6 ounces
88 / 5 = 17.6
The remainder can round the answer to 18 (five or more raise the score -- four or less let it rest) but the 88 ounce bag of popcorn will not be even if everyone gets 18 ounces of popcorn
If everyone were to get 18 then the bag a popcorn would have to have 90 ounces of popcorn in it
*Side note: 8 ounces is 1 cup

Annie is buying new school supplies. She has a budget of $45, and she has already spent $21. She wants to spend the remaining money on notebooks that cost $4 each. What is the greatest number of notebooks, x, Annie can purchase while staying within her budget?
Part A: Write an inequality to represent the situation.
Part B: Solve the inequality. Show all of your work.
Part C: Interpret the solution in terms of the problem.
Answer:
Part A) 45-21 ≥ 4x
Part C) She could buy up to 8 notebooks
Step-by-step explanation:
She already spent $21 so you would need to subtract that from the total budget. The sign would be greater than or equal to since that's the max amount.
45-21 ≥ 34
34≥4x
Divide both sides by 4 to cancel it out. You would get 8.5 but since you can't buy half a notebook it would be 8.

Select the correct answer, a plastic bin contains red, yellow and green key chains. Out of 350 key chains, 10% are yellow. Of the remaining key chains, 3/5 are green. How many red key chains are inside the bin?
A. 26
B. 35
C. 126
R. 189
Answer:
c
Step-by-step explanation:
Answer:
ed+green+yellow=350
10% out of 350 are yellow
0.1 times 350=35
350-35=315
3/5 out of 315 are green
red is not green so
2/5 of what is left is red
2/5 of 315 is red
2/5 times 315=430/5=126
126 red
