Answer:
A= 4
B= 18
This is just basic math, so I didn't write it out step by step. I also didn't use a specific method in math, so I can't answer those questions for you. But there is the answer to the actual question.
Answer:
This is a Simultaneous Equation
Now
We'll solve by Substitution.
a + b=22 ------(i)
3a + b = 30 -----(ii)
From (i)
Make b the subject
b= 22–a
Substitute b=22–a into equation (ii)
3a + b= 30
3a + (22–a)=30
3a + 22 – a= 30
3a - a = 30 -22
2a = 8
a= 4.
Now put a=4 into any equation of your choice to get b.
let's take equation (i)
a + b = 22
4 + b=22
b= 22-4
b=18.
FINAL ANSWER
a=4
b=18

Francis is half of Tyler's age (t).
Francis just turned 9.
Choose the equation that correctly models this situation.
9 = 1/2t
9 = 2t
2 + t = 9
t - 9 = 1/2
Answer:9=1/2t
Step-by-step explanation:
Francis age = 9
Her age is half of Tyler’s which is t
So 1/2 of t is 9

Describe the process for taking a set of data and creating a circle graph from it.
Answer:
Circle graphs
A circle is the same as 360°. You can divide a circle into smaller portions. A part of a circle is called an arc and an arc is named according to its angle.
A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.

The top and the bottom plots have the title Mathematics Students and Science Students respectively. Below the line for each dot plot is written Mark. The markings on each line are from 30 to 50 at intervals of 1. For the top plot there are two dots each for 34 and 40 and 1 dot each for 32, 33, 35, 37, and 39. For the bottom plot there are 2 dots each for 43, 46 and 49 and 1 dot each for 41, 42, and 47. Based on visual inspection of the dot plots, which group of students appears to have the larger average score? The mathematics students The science students Both groups are similar. Not enough information is available to draw a conclusion.
Answer: The science students.
