Thirteen more than three times a number is 25.
Answer:
x = 4
Step-by-step explanation:
Equation: 3x + 13 = 25
Step 1: Subtract 13 from both sides.
3x + 13 = 25
- 13 - 13
3x = 12
Step 2: Divide both sides by 3.
3x = 12
3 = 3
x = 4
Ricardo ran four miles in 31 minutes. It took him 6.25 minutes to run the first mile. Ricardo ran the remaining miles at a slow and steady speed. How long did it take him to run each of the last three miles?
Answer:
8.25 minutes
Step-by-step explanation:
31 minutes-6.25 minutes=24.75 remaining miutes between the last 3 miles so then you take 24.75 minutes÷ 3 miles remaining= 8.25 minutes each last 3 miles
How do you multiply monomials with the same base?
9514 1404 393
Answer:
multiply their coefficients, use the base with the sum of exponents
Step-by-step explanation:
The coefficients multiply. The base gets an exponent that is the sum of the exponents of the factors.
(a·x^b)(c·x^d) = ac·x^(b+d)
_____
If you remember that an exponent is simply an indicator of the number of times the base is a factor, this should be fairly clear. The usual associative and commutative properties of multiplication apply.
Example
5x^2 · 7x^3= 5·x·x·7·x·x·x
= 5·7·x·x·x·x·x
= (5·7)(x^(2+3))
= 35x^5
Kaden, Keith, and Kipp compete in a series of daily 3-way races. For each race, the probability that Kaden wins is 1/6, the probability that Keith wins is 1/2, and the probability that Kipp wins is 1/3. On a day that Kaden doesn't win, what is the probability that Keith beats Kipp?
9514 1404 393
Answer:
3/5
Step-by-step explanation:
Let a, b, c represent the probability of a win by Kaden, Keith, and Kipp, respectively.
P(bc' | a') = P(a'bc')/P(a')
P(bc' | a') = (1/2)/(1 -1/6) = (3/6)/(5/6) = 3/5
The probability is 3/5 that Keith beats Kipp when Kaden doesn't win.

Solve to find X. 3 ≥ -3x
Answer:
-1 ≤ x
Step-by-step explanation:
You just need to divide -3 on both sides.
-1 ≤ x
Note that since you are dividing by a negative number, the sign flips.
-1 ≤ x
Step-by-step explanation:
First start with the equation:
3 ≥ -3x
divide by -3 to get x positive and singular:
-1 ≥ x
and since we divided by a negative we need to flip the sign:
-1 ≤ x would be your answer

What is the slope of a line that is perpendicular to the line in the graph?
Answer:
The slope of the required line is 1
Step-by-step explanation:
The Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The graph shows a line whose slope can be calculated by selecting two points it goes through. Let's pick points (0,0) and (2,-2). Thus the slope is:
[tex]\displaystyle m=\frac{-2-0}{2-0}=-1[/tex]
The slope (m') of a line that is perpendicular to the line in the graph can be found by using the equation:
m*m'=-1
Solving for m':
[tex]m'=-\frac{1}{m}=-\frac{1}{-1}=1[/tex]
Thus the slope of the required line is 1
you buy 1 balloon and 1 banner for $4. your friend buys 3 balloons and 2 banners for $9.
each ballon costs: ?
each banner costs: ?
Answer:
each balloon costs 1$ and each banner costs 3$
Step-by-step explanation:
The costs of each balloon and banner are $1 and $3 respectively.
What is a system of equations?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given that, you buy 1 balloon and 1 banner for $4. your friend buys 3 balloons and 2 banners for $9.
Let x represents balloons and y represents banners.
Establishing the equations,
x+y = 4
x = 4 - y......(i)
3x + 2y = 9...(ii)
Put eq(i) in eq(ii)
3(4 - y) + 2y = 9
12 - 3y + 2y = 9
y = 3
Put y = 3 in eq(i)
x = 4-3
x = 1
Hence, the costs of each balloon and banner are $1 and $3 respectively.

What is the total area of the shaded region? Type just the answer in the blank.
Answer:
240cm
Step-by-step explanation:
6cm*14cm= 84cm
6*6=36
84+36=120*2=240
Answer:
7cm x 8cm
Step-by-step explanation:
The 14cm x 12cm box (top 'box 1') intersects with the 14cm x 12cm box (bottom 'box 2').
Half the values of each side are subtracted from one another, so
horizontal length: 14/2 = 7cm
vertical length: 12/2 = 6cm
Box 2 horizontal length (total) = 14cm devided by half the length of box 1 (7cm)
14 - 7 = 7cm
Box 2 vertical length (total) = 12cm devided by half the length of box 1 (6cm)
12 - 6 = 6cm
The total area is calculated by multiplying the horizontal and vertical lengths
7x6 = 42
the answer is 42

All cabins on the Giant Ferris Wheel are numbered in order starting from the number 1. Jack came and sat in cabin 48. Jim skipped the next 15 cabins and sat in cabin 2. How many cabins are there
Answer:
61 cabins
Step-by-step explanation:
Since Jim skipped 15 cabins and ended up sitting in cabin 2 that means he finished the number of cabins available and passed it by 2 cabins. Meaning that if we subtract 2 cabins from the 15 he skipped that would mean that from where Jack is sitting there are only 13 more cabins available. Now we simply add the 13 cabins to the number of cabins that Jack is sitting in to calculate the total number of cabins.
48 + 13 = 61
Step-by-step explanation:
62 cabins. Jack is skipping the next 15 cabins, so, in reality, you are adding 14 to 48.
6051 was rounded to the nearest one. What is the lower bond ?
Answer:
6050.5
Step-by-step explanation:
The key to this is "rounded to the nearest one"
If the question was to say "round to the nearest 10" you would do 10÷2 = 5
Always divide by 2
1 ÷2 = 0.5
6051 - 0.5 = 6050.5
If it was upper bond it would be:
6051 + 0 5 = 6051.5

Ted has a part-time job.
He is paid £7.90 per hour.
Last week he worked for 15/2 hours.
Work out Ted's total pay for last week.
Answer:
The answer is 122.45
Step-by-step explanation:
So basically we know that he worked 15 and 1/2 hours
He gets paid £7.90 for every hour he works
7.90 × 15 = 118.5
Then you do half of £7.90 which is £3.95 because he worked 1/2 hours half of 60 minutes is 30 minutes that why you half £7.90.
You add 118.5 + 3.95 = £122.45
