x-3y-7=0 , 3x-3y-15=0 solve this using cross multiplication
Answer:
x = 4 , y = -1
Step-by-step explanation:
x - 3y = 7 -- (1)
3x - 3y = 15 -- (2)
Rewriting (1), x = 3y + 7 -- (1)'
Substituting (1)' into (2),
3 ( 3y + 7 ) - 3y = 15
9y + 21 - 3y = 15
6y = -6
y = -1 -- (3)
Substituting (3) into (1),
x - 3 ( - 1 ) = 7
x + 3 = 7
x = 4 -- (4)
According to (3) and (4),
x = 4 , y = -1

I've been working all day so please now I ask you guys to help me, please I am starving
:(
Answer and Step-by-step explanation:
For the first one, x is equal to 61 (180 - 63 - 56 = 61)
and y = 4
51 = 12y + 3
48 = 12y
y = 4
For the second one,
x = 11
11x - 4 = 117
11x = 121
x = 11
y = 5
17y - 8 = 12 + 13y
4y = 20
y = 5

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain.
Answer:
If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

PLZZZZZ HELP ME! The volume of a suitcase is 4,331.25 inches. The length of the suitcase is 22.5 inches inches and the width is 19.25 inches. What is the height? Show your work.
Answer: 10 inches.
Step-by-step explanation:
v=l*w*h
Let’s plug in your numbers:
4,331.25=22.5*19.25*h
Let’s simplify it.
4,331.25=433.125*h
Then divide both sides by 433.125 (.125=1/8 by the way).
10=h

Solve 3x+8=2x+21
Full expansion
Answer:
x = 13
Step-by-step explanation:
3x + 8 = 2x + 21
shift the numbers to make them like terms . Here shift 2x to left hand side when u shift positive becomes negative 2x . and shift positive 8 to right hand side then it become negative 8
3x - 2x = 21 - 8
subtract like terms
x = 13

Jesse has reached 16% of his weekly reading time goal so far this week. If he has read for a total of
32 minutes this week, what is his weekly reading time goal in minutes?
x = time goal
16% = .16
.16 x = 32
x = 32/.16 = ___________ minutes
Jesse' weekly reading time is an illustration of ratio and proportion.
Jesse' weekly reading time is 200 minutes
Represent the reading time with x.
16% of his weekly reading time is given as 32 minutes
This is represented using the following equation
[tex]16 \% \times x = 32[/tex]
Express 16% as decimal
[tex]0.16\times x = 32[/tex]
Divide both sides by 0.16
[tex]x = 32/0.16[/tex]
[tex]x = 200[/tex]
Hence, Jesse' weekly reading time is 200 minutes

Because it’s the only sequence that have a common difference
The correct sequence which is an arithmetic sequence is,
⇒ 6, 13, 20, 27, 34
Hence, Option A is true.
What is Arithmetic sequence?An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.
We have to given that,
To find an arithmetic sequence.
For option A;
A. 6, 13, 20, 27, 34
Common difference is,
13 - 6 = 7
20 - 13 = 7
27 - 20 = 7
Thus, The correct sequence which is an arithmetic sequence is,
⇒ 6, 13, 20, 27, 34
Hence, Option A is true.

Answer:
P(black): 4/9
P(yellow): 2/9
P(orange): 3/9
Step-by-step explanation:
There are 4 black cubes, 2 yellow cubes, and 3 orange cubes. Add all of the cubes together to know how many cubes there are total.
4+2+3 = 9
Now that you know there are 9 cubes, you see how many black cubes you can draw out of 9. You can draw 4 black cubes out of the 9 total cubes, so the probability is 4/9.
You see how many yellow cubes you can draw out of 9. You can draw 2 yellow cubes out of the 9 total cubes, so the probability is 2/9.
You see how many orange cubes you can draw out of 9. You can draw 3 orange cubes out of the 9 total cubes, so the probability is 3/9.
Answer:
5) 4/9
6) 2/9
7) 3/9

A student is trying to calculate his semester average. He knows that his test average is an 80, his quiz average is a 72, homework is a 90, and classwork is a 93. If tests and quizzes are worth 30% each, and homework and classwork are worth 20% of his overall average, what is his average? Round to the nearest tenth.
What is the mean?
As per linear equation, the average of the student is 82.2.
The mean is 83.75.
What is a linear equation?A linear equation is an equation that contains one or multiple variable with the highest power of the variable is one.
The student got test average of 80, his quiz average of 72, homework of 90, and classwork of 93.
Test is worth of 30%.
Therefore, the weightage of test is
= 80 × 30%
= 24
Quiz is worth of 30%.
Therefore, the weightage of quiz is
= 72 × 30%
= 21.6
Homework is worth of 20%.
Therefore, the weightage of homework is
= 90 × 20%
= 18
Classwork is worth of 20%.
Therefore, the weightage of classwork is
= 93 × 20%
= 18.6
Therefore, the average of the student is
= (24 + 21.6 + 18 + 18.6)
= 82.2
Now, the mean is
= (80 + 72 + 90 + 93)/4
= 83.75
