5(x-2)= 3(x+4)

What is the answer to this equation?

Answers

Answer:

x = 11

Step-by-step explanation:

5x-10=3x+12

5x-3x=12+10

2x=22

x =11

The answer to this equation is x=11

5(x-2) = 3(x+4)

5x-10 = 3x+12
-3x -3x

2x-10 = 12
+10 +10

2x = 22

x= 11

Assuming no more snow was falling, how much snow would Ellie have on her lawn 4 hours after the snow began to melt? How much snow would Ellie have on her lawn after tt hours of snow melting?

Answers

Answer:

12 inches

Snow after 4 hours:

starting amount =  16

melted snow=   inches per hour×4

=

4

final amount=  starting amount−melted snow

=  16−4

=12

​

Snow after t hours:

starting amount=  16

melted snow=  inches per hour×t

=1×t

=1t

final amount=  starting amount−melted snow  =16-1t

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Seven people are going to share an 84-ounce bottle of soda.

Let x be the number of the ounces bottle of soda of each person.

Then we have the equation will be

7x = 84

 x = 84 / 7

 x = 12

Then the number of ounces will each person get to drink will be 12.

Which is the graph of y= 3/4x - 3?

Answers

The answer is Graph A.

The equation is written in slope-intercept form y=mx+b, so the slope m is 3/4, and the y-intercept is -3.

You can immediately eliminate graph B because its y-intercept is 3, not -3.

Then, you can count the rise/run for the other two graphs to see which one has a rise/run of 3/4. That’s graph A (graph C has a rise/run of 3/2, so it’s wrong).

If £29 =500 rubles how many £ are in 1,260 give your answer to 2dp

Based on the information given, it should be noted that the value of 1260 will therefore be £73.09.

Solving equations

From the information given, it was stated that £29 =500. Therefore, the equation to solve that of 1260 will go thus:

£29 =500

£1 = 500/29

£1 = 17.24

Therefore, 1260 will be:

Line segment GH is divided by point J in the ratio of 1:4. Endpoint G is at (7,5) and point J is at (10, 14).
What are the coordinates of endpoint H?
1. (57,75)
2. (-5, -31)
3. (22,50)
4. (78,90)

Answers

Answer:

(x2 , y2) = (22,50)

Step-by-step explanation:

Given:

m1 : m2 = 1:4

(x1 , y1) = (7 , 5)

(X ,Y) = (10 ,14)

Find:

(x2 , y2)

Computation:

X = (m1x2 + m2x1) / (m1+m2)

10 = [(1)(x2) + (4)(7)]/(1+4)

10 = [x2 + 28]/5

22 = x2

Y = (m1y2 + m2y1) / (m1+m2)

14 = [(1)(y2) + (4)(5)]/(1+4)

14 = [y2 + 20]/5

70 = y2 + 20

50 = y2

(x2 , y2) = (22,50)
