PLS HELP- Richard and Teo have a combined age of 33. Richard is 15 years older than twice Teo's age. How old are Richard and Teo?
Answer:
Teo= 9
Richard= 24
Step-by-step explanation:
x= Richard
y= Teo
33-15= 18
18÷2= 9
15+9=24
Teo is 6 years old and Richard is 27 years old.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
Let x be Teo's age, then Richard's age is 15 years older than twice Teo's age, or 15 + 2x. The combined age of Richard and Teo is 33, so we can write an equation:
x + (15 + 2x) = 33
Simplifying and solving for x, we get:
3x + 15 = 33
3x = 18
x = 6
So Teo is 6 years old and Richard is 15 + 2(6) = 15 + 12 = 27 years old.

Graph the image of the figure using the transformation given.
(its multiple choice!)
The original image undergoes reflection across x=-3.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
In the given graph DEFG is the original image.
D'E'F'G' is the new image after the transformations applied.
A reflection is defined by the axis of symmetry or mirror line. In the above diagram, the mirror line is x = -3.
Under reflection, the shape and size of an image is exactly the same as the original figure.
This type of transformation is called isometric transformation.
Hence, the original image undergoes reflection across x=-3.

At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual. What percentage of the usual price is the savings? Explain or show your reasoning. Use whatever strategy you would like.
Answer: 15%
Step-by-step explanation:
The usual price is $80.
This week however, the set sold for $12 less than this usual price of $80.
Savings therefore are $12 because people save $12 by buying it at $12 off.
Percentage of usual price:
= Savings / Usual price * 100%
= 12 / 80 * 100%
= 0.15 * 100
= 15%

Vivian needs to ride her bike to her friend’s house 96 miles away. She is riding at an average speed of 15 miles per hour. She has 6 hours to get there. Will she make it?
Answer:
No.
Step-by-step explanation:
If she is riding 15 miles per hour (the rate), and she has six hours (the time), then in order to find out the distance, we multiply the rate*the time.
15*6 = 90
90<96
So, no, she will not make it.

About 0.2of all the students in the fifth grade are boys. If the fifth grade has 75 students, how many of the students are ?
Answer:
15 boys
Step-by-step explanation:
About 0.2of all the students in the fifth grade are boys. If the fifth grade has 75 students, how many of the students are boys?
The number of boys can be calculated as:
0.2 × Number of fifth grade students
Number of fifth grade students = 75 students
Therefore,
The number of boys =
0.2 × 75 students = 15
The number of boys = 15 boys

Work out the probability that Ria takes one counter of each colour.
You must show your working.
Please show the full working out so I know how to get full marks in future I’ll give brainiest
Answer:
7/18
Step-by-step explanation:
Probability is the ratio of the number of possible outcomes to the number of total outcomes.
Given that there are 9 counters in a bag, 7 are green while 2 are blue.
the probability of picking at random a
Green counter = 7/9
Blue counter = 2/9
The probability that Ria takes one counter of each colour if 2 counter are picked as random is Green and Blue or Blue and Green
This is
=7/9 * 2/8 + 2/9 * 7/8
Recall that when a counter is picked the number of that ball available reduces and so does the total number of counter
=14/72 + 14/72
= 28/72
= 7/18

Max completed 140 questions on DFM last week.
This week, Max completed 182 questions.
Find the percentage increase.
Answer:
30%
Step-by-step explanation:
182-140=42(increase)
increase ÷ original × 100 %
= 42÷140×100%
=30%
The percentage increase from the old number to new number is 30 percent.
Given that, Max completed 140 questions on DFM last week. This week, Max completed 182 questions.
We know that, percentage increase = (New Number - Original Number)/Original Number ×100
= (182-140)/140 ×100
= 42/140 ×100
= 4200/140
= 30%
Therefore, the percentage increase is 30 percent.
