Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.
Answer:
(2, 0 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 4 → (1)
3x - 7y = 6 → (2)
Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x
6x + 9y = 12 → (3)
- 6x + 14y = - 12 → (4)
Add (3) and (4) term by term to eliminate x
0 + 23y = 0
23y = 0
y = 0
Substitute y = 0 into either of the 2 equations and solve for x
Substituting into (1)
2x + 3(0) = 4
2x = 4 ( divide both sides by 2 )
x = 2
solution is (2, 0 )

X, Y and Z are partners in a firm in the ratio of 1/2 :1/3:1/6
Y retires from business and
X and Z purchase his share of profit in the ratio of 3:2. Find out new ratio
Answers
Answer:
6:2
Step-by-step explanation:
X share from old ratio is 1/2
Y share from old ratio is 1/3
Z share from old ratio is 1/6
Now, we are told Y retires and that X and Z purchase his shares.
Thus;
Amount X took from Y = 1/2 × 1/3 = 1/6
Amount Z took from Y = 1/6 × 1/3 = 1/18
Thus, new share of X is now; 1/6 + 1/2 = 2/3
New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9
Ratio is now X:Z = 2/3 : 2/9 = 6:2

m=3 and through (2, -1) in slope-intercept
Answers
Answer:
y = 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, then
y = 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = 3x - 7 ← equation of line

Answers
Answer:
(i) 4r + 3p (ii) 3q - 2p when 3q > 2p (iii) 2y + 2/3 x [not sure what [3] means]
Step-by-step explanation:
So for part (i) 3 multiply p added to 4 times r = 3p + 4r
For part (ii) since subtraction can seem like a negative number you stipulate that 3q is greater than 2p so that is will hold true!
(iii) I'm not sure what the [3] means but just using the numbers [tex]\frac{2}{3}[/tex]x, since of means multiply and add 2y then you have 2y + [tex]\frac{2}{3}[/tex] x

The circle graph shows how Tremaine divided his time on the computer last week.
Tremaine used the computer a total of 30 hours last week. How many more hours did Tremaine use the computer to play games than to do research?
A. 1.5 hours
B. 20 hours
C. 6 hours
D. 7.5 hours
Answers
Answer:
A:1.5 hours
Step-by-step explanation:
all you have to do is figure out 5% of 30 which is 1.5
The required number of hours more, Tremaine uses the computer to play games than to do research is 6 hours.
What is the percentage?The percentage is the ratio of the composition of significant value to the overall composition of significance value multiplied by 100.
Here,
As mentioned in the question Tremaine used the computer for a total of 30 hours last week.
So from the circle graph:
Hour spend on games = 25% of 30
= 0.25 * 30
= 7.5 hours
Hours spend on research = 5% of 30
= 1.5 hours
Thus, the required number of hours more, Tremaine uses the computer to play games than to do research is 7.5 - 1.5 = 6 hours.

Jomaya has $15. She saves $2 every day. How many days will it take Jomaya to save $25?
Answers
Answer: 12.5
Step-by-step explanation: 2times 12.5 is 25
Answer:
5 days
Step-by-step explanation:
To find out this question, we can subtract the amount she wants to get, 25, by the amount she has, 15:
25 - 15 = 10
So, Jomaya wants to save up $10, and because she saves $2 every day, we can divide:
10 / 2 = 5
So, it will take Jomaya 5 days to save $25

slope and y-intercept of the graph of 25x -20y =100
Answers
Step-by-step explanation:
First, we need to put this standard form into slope-intercept form
To do this you need to move the "y" to all by itself
-25x+25x-20y=100-25x
-20y=100-25x
y=5/4x-5
Answer:
y=5/4x-5
The slope is-5/4 and the -intercept is (0,5)
How to find the slop?
Locating the y-intercept on a graph requires knowing the value of y at x=0. This is where the graph intersects the y-axis.
25x−20y=100
20y = 100 + 25x
20y=100+25x
y = [tex]5 + \frac{5}{4}[/tex]
She concluded that the slope is [tex]\frac{5}{4}[/tex]
and the y-intercept is (0,5).
y = mx + b where m is the slope and b is the y-intercept. So, the slope is 5/4 and the y-intercept is -5.
The slope is-5/4 and the -intercept is (0,5)
Finding the value of y at x=0 will allow you to locate the y-intercept on a graph. The graph's intersection with the y-axis occurs here.To learn more about slop refer to:

The letters P-R-O-B-A-B-I-L-I-T-Y are written on a set of cards. You mix the cards thoroughly. Without looking, you draw one letter then you draw another without replacing the first. Find the probability that you will select a P followed by a Y.
P(P, then Y) =
Answers
Answer:
P(P, then Y)=(1/11)(1/10)=1/110
Step-by-step explanation:
The number of letters in probability is 11.
There is 1 P.
The probability of drawing a P on draw 1 is the number of ways of drawing a P, which is 1, divided by the number of ways of drawing any letter, which is 11. Thus:
Probability of drawing a P on the first draw is 1/11.
There are now 10 letters left. There is 1 Y. so
Probability of drawing a Y on the second draw given that you drew a P on the first draw is 1/10.
The probability of drawing a P on the first draw and a Y on the second draw is
(probability of a P on draw 1)(probability of drawing a Y on draw 2, given a P on draw 1)
P(P, then Y)=(1/11)(1/10)=1/110
