Answer:
1) 7 in
2) 11x=-7
3)2y - 7 + 3y = 5
4) i DONT'KNOWN
Step-by-step explanation:
1)
step 1
the length of the rectangle is 1 inch less than twice its width ( in other words , you have to subtract 1 to twice the width to get the length)
Let
L represents the length
W represent the width
Hence
Twice width= 2w
Now , replace
L=2w-1 equation (1)
Also
The perimeter =40 inches
[tex]perimeter= 2(L+W) 40=2(L+W) equation (2)[/tex]
Step 2
Solve for w
Replace equation (1) in equation (2)
[tex]40=2(L+W) equation (2)\\40=2((2W-1)+W)\\40=2(3W-1)\\40=6W-2\\Add 2 in both sides\\40+2=6W-2+2\\42=6W\\Divide both sides by 6\\\frac{42}{6}=\frac{6W}{6} \\7=W[/tex]
so ,the width is 7 in.
2) Given the equations
[tex]x+5y=3\\2x-y=-2[/tex]
The first step is to multiply the second equation by 5 (both sides of the equation)
[tex]5(2x-y=-2)\\5(2x-y)=5.(-2)\\5.2x-5.y=-10\\10x-5y=-10\\[/tex]
Next is to add both equations
x+5=3 +10x-5y=-10 = 11x+0y=-7
The result is 11x=-7
3)[tex]x+3y=5\\x+7=2y[/tex]
To make a substitution for x using the second equation in the first equation you :
1. solve for x the second equation
Subtract 7 in both sides of the equation:
[tex]x+7-7=2y-7\\x=2y-7\\[/tex]
2.Substitute the x in the first equation for the value of x you get in step 1 :
[tex]2y-7+3y=5[/tex]

What is the value of 100?
Answers
Answer:
10
Step-by-step explanation:
Means back the numbers into multiples of several small numbers
Like:; 1. We take LCM of 40
Just break into multiples of small number
40= 2×2×2×5
2. We take LCM of 50
50= 5×5×2
So LCM for 100 is 2×2×5×5
after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)
Then write the the single number in place of two multipled numbers
Like:; 2×2 is written as 2 // 3×3 is written as 3
So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)
write pairs in single number 2×5
And so we get 2×5=10
So we find root of 100 that is 10

Which line has a slope of 0.625, and which line has a slope of 1.6?
Explain why the slopes of these lines are 0.625 and 1.6.
Answers
Answer:
The answer is below
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b; where y and x are variables, b is the y intercept (i.e. value of y when x is zero), m is the slope of the line.
The slope of a line passing through the points [tex](x_1,y_1)\ and\ (x_2,y_2)\ is:[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let the point where the two lines intersect be the origin (0, 0).
Line 1 passes through (0, 0) and (8, 5). Hence:
slope of line 1 = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{5-0}{8-0} =0.625[/tex]
Line 2 passes through (0, 0) and (5, 8). Hence:
slope of line 2 = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{8-0}{5-0} =1.6[/tex]

the second option is the one that i calculated second, so i knew that i could rule out the last one my default.
just for kicks, if we multiplied the third option, it would come out to 8 + 4x.
