Answer:
I dont know what you are supposed to answer with but I'll try to help you out. I take it that you have to find the letter ex. the letter d in 1/2d = 7. What you have to do is to get the d by itself and in order to do that you must move the 1/2 over to the 7. So what you would have to do is take the fraction that has the letter on it and move it to the whole number side or the side without the letter but without moving the d.The d stays on one side while the other numbers are on the other side. When you move the 1/2 over it should look like this sort of due to the limitations of only being able to use text: d = 7 ÷ 1/2. Now after that you have to divide 7 by 1/2 or .5 for question 13 in this instance. Your answer for 13 should be this: d=4.5Makesuretoshowallyourworkjustincase.
13. d = 4.5
14. 18 = f
15.-9=s
16.-24 = r
17. 0.125 = y
18. -3 = v

O B. -x2 + 4x + 6
O c. 4x2 - 19
O D. - x2 + 4x - 4
Answer:
I think it's going to be D
Step-by-step explanation:
4x+1=2x-5
-4x-1 -4x-1
-2x=-4
÷2
x=-2
Create a proportion: 8000/4 = 7000/x
8000x = 28000
then divide
8000x/8000 = 28000/8000
that equals x = 3.5 tons
---------------------------------------------------------OR---------------------------------------------------
Create a proportion 8000/4 = 7000/x
then simplify to 2000/1 = 7000/x
7000 = 2000x
then divide
7000/2000 = 2000x/2000
3.5 tons = x
Answer:
Yes i can be on any side.
2,160 minutes
Given:
Question:
The Process:
The following are the steps to form the expression.
Let us solve the expression.
Thus she takes 2,160 minutes to complete her sewing project.
- - - - - - - - - -
The following are the complete steps.
Step-1:calculating the total perimeter of the border around 2 rectangular tablecloths
Recall the perimeter of a rectangle.
Hence the perimeter of a rectangular tablecloth is 30 feet.
So, the total perimeter of the border around 2 rectangular tablecloths is
Step-2:converting feet to inches
Recall that
Let us convert 60 feet to inches.
Step-3:calculating minutes will it take her to complete her sewing project
She takes 3 minutes to sew on 1 inch of the border of a tablecloth. There are 2 rectangular tablecloths.
Thus she takes 2,160 minutes to complete her sewing project.
Keywords: Frances is sewing, a border, around, 2 rectangular tablecloths, that each measure 9 feet long by 6 feet wide, takes, 3 minutes to sew, 1 inch of border, how many, minutes, to complete her sewing project, write an expression, to solve it
Answer:
The value of x is 6
Step-by-step explanation:
we know that
If two angles are supplementary, then their sum is equal to 180 degrees
so
In this problem
m∠C+m∠E=180°
we have
m∠C=112°
m∠E=(3x+50)°
substitute and solve for x
112°+(3x+50)°=180°
3x+162=180
3x=180-162
3x=18
x=6
