Jordan is mowing lawns to save money for the Camp Rodeo Field Trip. The total cost for the excursions, travel, and food will be $130. Jordan has already saved $50. Which of the following equations represents how much more money Jordan needs to save in order to go on the field trip?
A. x + 50 = 130
B. x - 50 = 130
C. x - 130 = 50
D. x = 50 + 130
Answer:
X + 50 = 130
Step-by-step explanation:
This is actually a subtraction equation although addition is how you set it up initially. X is the variable. You already have $50. You need $130.
To solve, subtract 50 from each side,
X + 50 - 50 = 130 - 50, and simplify,
X = 120.
Jordan will need $120 more to go to the Camp Rodeo Field Trip.
Hope this helps.

Katherine uses $\frac{7}{10}$ of a gallon of red paint to paint $\frac{3}{5}$ of her wall. How many gallons of red paint will she use to paint her whole wall? There is no 5/5
Answer:
1.167 gallons
Step-by-step explanation:
Given that:
Fraction of red paint used = 7/10 of a gallon
Fraction of wall painted = 3/5
Gallon of paint required to paint the entire wall:
Fraction of entire wall = 1/1
7/10 paint = 3/5 wall
x paint = 1 wall
Cross multiply
(3/5)x = 7/10
Divide both sides by 3/5
3/5x ÷ 3/5 = 7/10 ÷ 3/5
(3/5)x * 5/3 = 7/10 * 5/3
x = 35 / 30
x = 7/6 = 1.167 gallons of red paint
Amy earned $25 after babysitting for 3 hours. If she always charges the same rate, how much will she make after working for 7 hours?
Answer:
$58.33
Step-by-step explanation:
Set up a proportion where x is the amount she makes for 7 hours:
[tex]\frac{3}{25}[/tex] = [tex]\frac{7}{x}[/tex]
Cross multiply and solve for x:
3x = 175
x = 58.33
So, after working for 7 hours, she will make $58.33
Answer:
About 60-65$
Step-by-step explanation:
Because every 3 hours she gets $25 and she worked 7 hours so there's 6 in 7 hours so 25+25 is 50 and the other hour would be half of 25 so 12.5 so between 60-65. Im so sorry if its wrong hope it worked tho! <3

can be written as 5/2 divided by 10/3. I always use keep, switch, flip technique with fractions. keep 5/2 switch the division to multiplication, flip the 10/3 to 3/10
5/2 x 3/10 cross multiply
15/20 = 3/4
Answer:
It would be B. 3/4
Step-by-step explanation:
You turn the mixed numbers into improper fractions then you divide by using the reciprocal of the 3 & 1/3. This will leave you into the equation "5/2 * 3/10"
When multiplied, you will get "15/20" which simplifies to "3/4"

Find the probability of getting four consecutive aces when four cards are drawn without replacement from a standard deck of 52 playing cards.
Answer:
P=0.0000037
P=0.00037%
Step-by-step explanation:
Probability
A standard deck of 52 playing cards has 4 aces.
The probability of getting one of those aces is
[tex]\displaystyle \frac{4}{52}=\frac{1}{13}[/tex]
Now we got an ace, there are 3 more aces out of 51 cards.
The probability of getting one of those aces is
[tex]\displaystyle \frac{3}{51}=\frac{1}{17}[/tex]
Now we have 2 aces out of 50 cards.
The probability of getting one of those aces is
[tex]\displaystyle \frac{2}{50}=\frac{1}{25}[/tex]
Finally, the probability of getting the remaining ace out of the 49 cards is:
[tex]\displaystyle \frac{1}{49}[/tex]
The probability of getting the four consecutive aces is the product of the above-calculated probabilities:
[tex]\displaystyle P= \frac{1}{13}\cdot\frac{1}{17}\cdot\frac{1}{27}\cdot\frac{1}{49}[/tex]
[tex]\displaystyle P= \frac{1}{270,725}[/tex]
P=0.0000037
P=0.00037%

A track team has 4 runners on a relay team. If by coincidence each runner takes an average of 45.48 seconds to complete her leg of the relay, what is the total time to run the relay?
Answer:
181.92 seconds
Step-by-step explanation:
We are given that,
Time taken by each person in the team = 45.48 seconds
Number of members in the team = 4
It is required to find the total time taken by the team to finish the race.
Thus, the time taken taken = 4 × 45.48 = 181.92 seconds
Hence. the team finished the race in 72.4 seconds.
