Answer:
114
Step-by-step explanation:
Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)
19+1= 20
20 units= 120 (Data from 1st sentence)
1 unit= 120/20= 6
19 units= 120-6= 114 (Values solved in working above)
Ans: There are 114 red marbles.
The graph shows the relationship between distance driven and gallons of gas used.
Continuous graph on a coordinate plane shows distance driven, numbered 20 to 60 along the horizontal axis, and gallons of gas used, numbered 1 to 4 on the vertical axis. Solid circles appear at points (0, 0), (30, 1), (60, 2).
Use the graph to complete the statements.
The car gets
miles to the gallon.
After the car has traveled
miles, 2 and two-thirdsgallons of gas have been consumed.
Answer: 30 and 80
So the care gets *30* miles gallon.
After the car has traveled *80* miles, 2 2/3 gallons.
Answer:

Solve the inequality for x: 4x + 8 > 2(3x + 1)
Answer:
x < 3
Step-by-step explanation:
Step 1: Write inequality
4x + 8 > 2(3x + 1)
Step 2: Solve for x
Distribute 2: 4x + 8 > 6x + 2Subtract 4x on both sides: 8 > 2x + 2Subtract 2 on both sides: 6 > 2xDivide both sides by 2: 3 > xRewrite: x < 3Here we see that any value smaller than 3 will be a solution.

Answer the real-world problem below. Then, decide whether the answer is the GCF or the LCM. A local radio station is celebrating its 10th year on the air and is giving away prizes to callers. It is giving away a $10 bill for every 10th caller. It is also giving away free digital albums to every 8th caller. How many callers will call the radio station until someone wins both a $10 bill and a free digital album?
Answer:
LCMit will take 80 callsStep-by-step explanation:
The solution is LCM
the least common multiple of 10 and 8 are
10=10,20,30,40,50,60,70,80,90,........
8= 8,16,24,32,40,48,56,64,72,80,88..........
The least common multiple is 80
therefore it will take 80 callers to call in to win both the bills

What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expressions are:-
5-x/3 for x = -3
5 - (-3 / 3 ) = 6
-2 + 2x/3 for x = 6
-2 + (2 x 6 )/3 = 2
-3 + x/2 for x = 6
-3 + (6 / 2 ) = 0
2-3x/4 for x = 4
2 - ( 3 x 4 ) /4 = -1

is this reasoning inductive or deductive? explain why.
1. all pennies are copper. if your friend gives you a penny, you conclude that the penny is copper colored.
2. all even numbers are divisible by 2. 28 is even. therefore, 28 is divisible by 2.
please help me out with this and also include reasoning! thank you so much!
Answer:
No. 1 is inductive, cos the evidence is based on proberbility as not all pennies are silver color, since thier color could change over time (fade)
while
No 2 is deductive since all even numners are divisible by 2, there is a full assurance of the outcome.
Answer: The reasonings are deductive. They tried to do a trick question I think.
Step-by-step explanation: There both deductive because the first sentence has a key word which is Conclude. The word might not seem to matter until you look up what deductive means. Deductive and Inductive are different because one is specifics observation and then draw a conclusion and the other is specifics conclusion follows a general theory. And the key word in deductive is conclusion in the first sentence it says that you conclude. Deductive means a conclusion that follows a general theory. The deductive is following a general theory which means if the facts are right then the conclusion should be right. The deductive makes sense in the first because if the facts that all the pennies are copper is true then the penny your friend gave you should be copper. The second sentence same thing if the fact was right then any number that is even can be divisible by 2. So deductive makes sense in both sentences. Inductive makes sense it inside one on the sentences not both. Inductive makes sense inside the first because the person could have seen that the pennies were all made of copper. i think that it being deductive is a better choice that inductive and if you still are confused you can look up "difference between inductive and deductive reasoning" and go to images it should have a blue and pink picture of the definition of them. Sorry I wrote it so long you can just shortened it down for the answer.

3/4x + 2/5 = 4x - 1/4x
Answer:
4/45 = x
Step-by-step explanation:
Strongly suggest that you enclose the fractional coefficients inside parentheses to reduce possible ambiguity:
(3/4)x + 2/5 = 4x - (1/4)x
Consolidate the x terms on the right side and leave the 2/5 on the left:
2/5 = (4 - 1/4 + 3/4)x, or
2/5 = (4 1/2)x or 2/5 = (9/2)x
Solving for x: Multiply both sides by (2/9):
(2/9)(2/5) = (2/9)(9/2)x, or:
4/45 = x
