How do you solve this system by elimination? 2x + 4y =8

Answers

Answer 1

Answer:

The answer is x=−2y+4

Step-by-step explanation:

1) Add -4y to both sides.

2x+4y+−4y=8+−4y

2x=−4y+8

Step 2: Divide both sides by 2.

2x/2=−4y+8/2

x=−2y+4

Hope this helps

150m - 125m + 43,200 = 45,675 - 200m
Please help!! What is the value of m ?

Answers

first you combine like terms

25m + 43,200 = 45,675 - 200m

then you add 200m to both sides

225m + 43,200 = 45,675

then you subtract 43,200 from both sides

225m = 2,475

then you divide both sides by 225

m = 11

Answers

Answer:

because 25/100 = 1/4

0.20 = 20/100

Step-by-step explanation:

because 25/100 = 1/4

0.20 = 20/100

because 0.20 means 20 tenths 0.23 > 1/2

because 0.23 = 23

0.4 = 1/4

because they are on the same place on a number lin

A contractor can spend at most $250 a day on operating costs and payroll. It costs $45 each day to operate the forklift and $60 a day for each crew member. Write an inequality to represent the contractor's budget for the day.

Answers

Answer:

Step-by-step explanation:

The answer is B. His budget is $250 so it has to be less than or equal to. $60 a crew member (x = the crew members) and $45 to use the forklift, so $60x + $45 is less than or equal to $250

Answer:

B is the correct answer.

Step-by-step explanation:

According to the problem, the contractor can spend AT MOST $250 a day, meaning $250 is the limit. Therefore, that gives you less than or equal too, or ≤. Next, it costs $45 a day, including $60, which you would add to get the final amount, or +.

Therefore, 60x + 45 ≤ 250

Teri begins walking east at 2 miles per hour at 1:00 pm. If cindy leaves from the same point 30 minutes later walking east at 3 miles per hour, when will she catch teri

Answers

Answer:

One hour after  starting

Step-by-step explanation:

Let Teri walk at a rate of 2 miles per hour in time , t + 0.5, since it is 30 minutes ahead and 30 minutes = 0.5 hours, the distance he moves is d = 2(t + 0.5). Also, since Cindy moves at a rate of 3 miles per hour, and starts at time t, the distance d' she moves is d' = 3t.

Now, when they catch each other, the distance moved is the same.

So, d = d'

2(t + 0.5) = 3t

expanding the brackets, we have

2t + 2 × 0.5 = 3t

2t + 1 = 3t

collecting like terms, we have

3t - 2t = 1

simplifying, we have

t = 1

So, Cindy will catch Teri one hour after starting.

I'm not able to do it but I can tell you how

Step-by-step explanation:

make the 10a-9 equal 14a-25 solve for that a then use the answer to a to then plug in thst number in all of them and that would be your answer

The perimeter of the isosceles triangle is 88.

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, equilateral, isosceles and so on.

From the diagram, two sides of the triangle are equal, hence it is an isosceles triangle, hence:

10a - 9 = 14a - 25

4a = 16

a = 4

10a - 9 = 10(4) - 9 = 31

6a + 2 = 6(4) + 2 = 26

Hence the perimeter of the triangle = 31 + 31 + 26 = 88

Hence the perimeter of the triangle is 88.

Under a given correspondence two triangles are congruent if the three sides of the one are equal to the three corresponding sides of the other
The above is known as
(a)SSS congruence of two triangles
(b)SAS congruence of two triangles
(c)ASA congruence of two triangles (d)RHS congruence of two right-angled triangles​

Answers

Answer:

(a)SSS congruence of two triangles

Step-by-step explanation:

Congruence is a relationship that expresses the similarity between two triangles. The relationship between two triangles with their three sides being congruent is termed as the side-side-side (SSS) congruence property of the triangles. This implies that the two triangles are similar with respect to their three sides.

In corollary, since the three sides of the two triangles are congruent, then the three angles respectively would be congruent.

Answers

Answer:

  Bob

Step-by-step explanation:

The "steepness," or slope, of the mountain is the ratio of height to horizontal distance to the base:

  Joe's mountain slope = 1200/1500 = 0.8

  Bob's mountain slope = 900/1000 = 0.9

Bob's mountain has a greater slope than Joe's. Bob climbed the steeper mountain.

The measure of angle Q is 133 degrees

Step-by-step explanation:

(x + 13) + (10x + 13) + (2x - 2) = 180 //There are 180 degrees in a triangle

x + 13 + 10x + 13 + 2x - 2 = 180 //Remove parentheses

13x + 24 = 180 //Combine like terms

13x = 156 //Subtract 24 from each side

x = 12 //Divide to get value of x

10(12) + 13 = Measure of angle Q //We know Q is 10x + 13, since we know what x is 12 from the previous step we'll substitute x for 12

120 + 13 = Measure of angle Q //Multiple 10 and 12

133 = Measure of angle Q

Y=0.5x
I hope this might help

Answer:

y = - 2x

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 )

y = [tex]\frac{1}{2}[/tex] x + 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2

The perpendicular line passes through the origin ⇒ c = 0

The equation of line L₂ is

y = - 2x + 0 , that is
