Answer:
y=5
x=-1
Step-by-step explanation:
5x-2y=-15
3x+8y=37
add 2y to both sides
5x=2y-15
divide both sides by 5
x=(2y-15)/5
x=2y/5-3
substitute for x
3(2y/5-3)+8y=37
6y/5-9+8y=37
add 9 to each side
6y/5+8y=46
subtract 8y from both sides
6y/5=46-8y
multiply both sides by 5
6y=5(46-8y)
6y=230-40y
46y=230
y=5
substitute for y
5x-2(5)=-15
5x-10=-15
5x=-5
x=-1

Answer:
1: 2, 2: 3
Step-by-step explanation:
1 is 2 because if you count the total students, (25), divide by 2 to get 12.5 and round down. we want to find the 12th number. For the second one, do the similar thing, but now we have 13. Add the 13th and 14th numbers and divide by 2 to get 3.
Write 60/8 as a mixed number. Give your answer in its simplest form.
Answer:
60 above the division line is called the numerator and 8 below the divison line is called the denominator.
We call the line that separates 60 and 8 the division line. It is also known as the fraction bar or vinculum.
60/8 is an improper fraction because the numerator is greater than the denominator.
A mixed number is an integer (whole number) and a proper fraction.
Step-by-step explanation:
Answer: 7/ 1/2
Step 1: Find the whole number
We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.
60/8= 7.5 = 7
Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.
Step 2: Get the new numerator
To work this out we'll use the whole number we calculated in step one (7) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:
60 - (8 x 7) = 4
Step 3: Our mixed fraction
We've now simplified 60/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:
7
4
8
Step 4: Simplifying our fraction
In this case, our fraction (4/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 4 and 8 is 4.
We can now divide both the new numerator and the denominator by 4 to simplify this fraction down to its lowest terms.
4/4 = 1
8/4 = 2
When we put that together, we can see that our complete answer is:
7
1
2

Angle 1 and 2 are equal because of correspondence angle
so , (78-2x) = (89-3x)
x = 89 - 78
x = 11
hence angle 1 = ( 78 - 2*11) = 56
and angle 2 = ( 89-3*11) = 56
So, both of angle is 56

x + y will have negative value as
x + y = -4 + (-8) = - 4 - 8 = - 12
Answer:
A
Step-by-step explanation:
They are both negative so you will keep the negative sign when you add.
Them sum of two numbers is 17. One number is 3 less than 2/3 of the numbers. What is the lesser number?
Answer:
The smaller number is 5
Step-by-step explanation:
Let the smaller number be x
the other number is (17 -x) (we know they add up to 17)
2/3 of the bigger number is written as 2/3 (17 - x)
The smaller number is 3 less than that. (so subtract 3 to get x)
x= 2/3 (17 -x) - 3 <-- We have an equation, solve for x
Check 2/3 x 12 - 3 = 8 - 3 = 5
Add(2a + 8) + (4a + 5) pls show steps.

What is the equation of a line that passes through (-2, 1) and has a slope of -5/2 ?
Answer:
y=-5/2x-4
Step-by-step explanation:
y-y1=m(x-x1)
y-1=-5/2(x-(-2))
y-1=-5/2(x+2)
y=-5/2(x+2)+1
y=-5/2x-10/2+1
y=-5/2x-5+1
y=-5/2x-4
