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.
if you were to do a fraction graph, 2 of the 3 [tex]\frac{1}{3}[/tex] bars would be the same length of 4 [tex]\frac{1}{6}[/tex] bars:

What is the slope of this line?
Answer:
A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).

If you buy a car at a gash station for $5.00, the cost per gallon is $3.10. If you have $40, write and solve a linear equation to find the number of gallons of gas you can afford
Answer:
Step-by-step explanation:
1) Why would somebody buy a car at a gas station? For $5?
2) You would have $35 to spand on gas. 10 gallons would cost $31. Add 2 more gallons for $6.20.
The total is 12 gallons of gas for $37.20
42 = y + 15 whats y? y == __
Solution
[tex]y=27[/tex]
Step-by-step explanation:
Subtract [tex]15[/tex] from both sides of the equation:
[tex]42=y+15[/tex]
[tex]42[/tex][tex]-15=y+15[/tex][tex]-15[/tex]
Simplify:
Subtract the numbers:[tex]42-15=y+15-15[/tex]
[tex]27=y+15-15[/tex]
Subtract the numbers:[tex]27=y+15[/tex][tex]-15[/tex]
[tex]27=y[/tex]
Move the variable to the left:[tex]27=y[/tex]
[tex]y=27[/tex]
[tex]y=27[/tex]

Hailey took a taxi from her house to the airport. The taxi company charged a pick-up fee of $2.40 plus $4.50 per mile. The total fare was $87.90, not including the tip. Write and solve an equation which can be used to determine mm, the number of miles in the taxi ride.
Answer:
The taxi drove Hailey for 19 miles.
Step-by-step explanation:
1. Subtract the tip.
$87.90 - $2.40 = $85.5
2. Divide by the price per mile. ($4.50)
$85.5 / $4.50 = 19
one card from a deck of cards is selected, it is replaced, and another card is chosen. what is the probability that the first card is a red card and the second card is a diamond card?
Answer:
the probability of a red card is 1/2 of 50% chance. The chance of a diamond card is 1/4 or 25% chance
Step-by-step explanation:
Answer as a fraction = 1/8
Answer in decimal form = 0.125
Answer as a percentage = 12.5%
==========================================
Explanation:
The probability of choosing a red card is 1/2 since half of the cards are red (the other half are black).
This card is selected and then put back into the deck. This means that the second selection will deal with the same number of total cards.
Since we have four suits, and one of those suits is diamonds, this means the probability of choosing a diamond card is 1/4.
We then multiply the fractions to get (1/2)*(1/4) = (1*1)/(2*4) = 1/8
The probability of getting a red card first, then a diamond card second, is 1/8
Use your calculator to find that 1/8 = 0.125 which converts to the percent form 12.5%

Solve the following equation:
1.3(a + 2) + 5.6 = 17.3
Answer:
a=7
Step by step Explanation:
Step 1: Simplify both sides of the equation.
1.3(a+2)+5.6=17.3
(1.3)(a)+(1.3)(2)+5.6=17.3(Distribute)
1.3a+2.6+5.6=17.3
(1.3a)+(2.6+5.6)=17.3(Combine Like Terms)
1.3a+8.2=17.3
1.3a+8.2=17.3
Step 2: Subtract 8.2 from both sides.
1.3a+8.2−8.2=17.3−8.2
1.3a=9.1
Step 3: Divide both sides by 1.3.
1.3a 9.1
1.3 = 1.3
a = 7
