Solve this linear equation using substitution. (Please show work!)
y = -x
y= 3x - 4
Answer:Under↓↓↓
Step-by-step explanation:
-x=3x-4 (substitute -x for y)
-4x=-4 (Subtract 3x from both sides)
x=1 (Divide both sides by -4)
Since y=x then y=1
Answer:
X=1
Step-by-step explanation:
So if you look at the two y= equations, you'll see that you can make them equal two one another because they both equal y
Placing the -x in place of y for it to look like this; -x = 3x-4. Subtract the 3x to the other side to get -4x =-4. Then divide the 4 from the x to isolate it and you get x=1!
Hope that helps!

15 km
20 km
40 km
Coordinate graph with title Displacement versus Time for a Car, showing Time in hours from zero to five over horizontal axis and Displacement in kilometers from zero to twenty five over vertical axis. A line is plotted on the graph, starting from origin and peaking at twenty before moving toward horizontal axis and intersecting it at five
Answer:
It's right there on the graph ! At 5 hours, the displacement is zero.
"How can that be ?", you ask.
That's a great question.
The car started out, drove farther and farther from home for the first 4 hours, then drove back home during the 5th hour. It's all right there on the graph.

Explain how to compare two fractions that have the same numerator and different denominators. Use an example to help justify your response.
Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate..
Answer:
Step-by-step explanation:
2 fractions with the numerator and different denominators can be compared when you find the lowest common denominators (LCD. For example 1/2 and 1/3 have the same numerator, but the denominators are not so you have to find the LCD. The LCD, in this case, is 6, so the fractions would be 3/6 and 2/6 and now if you compare you can tell that 3/6 is greater than 2/6 so 1/2 is greater than 1/3.
Answer:
Answer is down below :D
Step-by-step explanation:
A numertator is the top number and the denominators are the bottom number of a fraction. You can tell the difference because if you look at the top number of one fraction and you look at the other that you're supposed to compare and there the same number, then they are the same. For example, 1/2 and 1/3 have the same numetators but not denominators. Now for denominators you have to look at the bottom number but if the two fractions you're comparing have the same bottom number then there the same, but if they have two different bottom numbers, then they are not the same. For example again: 1/3 and 1/9 The may seem the same but there not since the bottom number is different.
The football team has a total of 350 jerseys. There are 154 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys?
(answer this and show your work please)
_answer here_% are medium-sized jerseys.
(Type an integer or a decimal.)
Answer:
44%
Step-by-step explanation:
To find the percent of medium sized jerseys, divide the amount of medium sized jerseys by the total amount, then multiply it by 100:
(154 / 350) x 100
0.44 x 100
= 44
So, 44% are medium sized jerseys

I am not to familiar with diameter and radius, please help with 2.
Well since we know that its length and width is 8 and 10, and the perimeter is 36, we multiply those to get the diameter of the circle, then we use the formula r = d/2. Then that should get you the radius.

2,000 divided 20 =
what is the answer i need it
Answer:
Step-by-step explanation:
Cross out one zero on both sides, which would change the equation to 200/2=100
The answer to 2,000 divided by 20 is 100.
Division is the inverse operation of multiplication, so dividing a number by another is the same as finding the number of times the divisor can fit into the dividend.
When divide 2,000 by 20, essentially finding out how many times 20 fits into 2,000.
Since 20 goes into 2,000 exactly 100 times as:
20 x 100 = 2,000, that is the result is 100.
In this case, 20 fits into 2,000 precisely 100 times, resulting in a quotient of 100.
