Step-by-step explanation:
Simplifying
2y + -6 = 12
Reorder the terms:
-6 + 2y = 12
Solving
-6 + 2y = 12
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 2y = 12 + 6
Combine like terms: -6 + 6 = 0
0 + 2y = 12 + 6
2y = 12 + 6
Combine like terms: 12 + 6 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
Answer:
Y=9
Step-by-step explanation:
Subtract 6 from both sides. Simplify. Dive both sides of the equation by the same term. Simplify. Solution y=9

A photocopier can print 12 copies in 48 seconds. If the photocopier always copies at the same rate, how
long would it take to make 5 copies?
48 seconds / 12 copies = 4 seconds per copy
4 seconds per copy x 5 copies = 20 seconds
Answer: 20 seconds

Answer:
1) 62.5
2) 50
3) 75
4) 100
Step-by-step explanation:
1)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*4=100[/tex] days, there will be [tex](1/2)^{4}=1/2^{4}=1/16[/tex] of it left.
So, [tex]1000/16=\boxed{62.5}[/tex].
2)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*3=75[/tex] days, there will be [tex](1/2)^{3}=1/2^{3}=1/8[/tex] of it left.
So, [tex]400/8=\boxed{50}[/tex]
3)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*2=50[/tex] days, there will be [tex](1/2)^2=1/2^{2}=1/4[/tex] of it left.
So, [tex]300/4=\boxed{75}[/tex].
4)
The only answer left is [tex]\boxed{100}[/tex] grams. You can solve it the same way you solved the previous steps.

Answer:
Pizza 1: lenght(l)=16 and width(w)=4
Perimeter=40in.
Pizza 2: l=32 and w=2
Perimeter=68in.
Step-by-step explanation:
1. List down factors of 64.
64=1,2,4,8,16,32,64
2. Select the factors you'll be using to draw your rectangles. In this case I selected the factors 2,4,16 and 32 because area of rectangle=l×w. Therefore 2×32=64 and 4×16=64.
3. Draw your rectangles according to the measurements you chose. If the drawing is too big to fit the box you can simply use a scale. Such as 1 inch=4 inches on your drawing. For example, when drawing the length of the second Pizza which is 32in. you can simply draw a line of 8 inches.
4. After drawing your pizzas you niw have to find the Perimeter of both. Simply use the formula Perimeter of a rectangle=2(l+w)
Pizza 1: Perimeter=2(16+4)
=2×20
=40in.
Now do the same for Pizza 2 using its own lengjt and width. Hope this helped.
how can you solve this problem? 3x + 14 = 59. solve for x.
Answer:
x = 15
Step-by-step explanation:
3x + 14 = 59
subtract 14 from both sides
3x = 45
divide both sides by 3
x = 15
Answer:
15
Step-by-step explanation
Subtract 14 from both sides and the do 45 divided by 3 and it gives you your answer 15

Find the graphed solution to the inequality. 3(x-9) < -18
Answer:
[tex]x<3[/tex]
Step-by-step explanation:
[tex]3\left(x-9\right)<-18[/tex]
Divide both sides by 3
[tex]\frac{3\left(x-9\right)}{3}<\frac{-18}{3}[/tex]
[tex]x-9<-6[/tex]
Add -9 to both sides:
[tex]x-9+9<-6+9[/tex]

Can someone link a video or tell me how to do this?
Answer:
f = 29
Step-by-step explanation:
First look at the angle inside the triangle that has no marker. You can determine this angle using the angle on the opposite side (112).
A straight line will equal 180. So this angle would equal 180 - 112 or 68.
Now you know two of the triangles angles.... 53 and 68.
A triangle's inside angles always add up to 180 degrees.
53 + 68 = 121
The angle that is 2f + 1 must equal 180 - 121 which is 59 degrees.
2f + 1 = 59
2f = 58
f = 29
The three angles inside the triangle are 53, 68 and 59

Amy has 1275 less than her brother ben .then ben spends 550 and amy gets 750 . who has more money now?
Amy because Ben spend the less money then
amy get more money
Amy has more money than her brother after all transactions.
What is an equation and an expression?An equation is a statement that the depicts the values of two mathematical expressions as equal using an (=) sign. Example -
2x = 5
An expression is written using individual terms (either constant or variable) separated by mathematical operations. Example -
3x + 5y + 3
We have Amy who has $1275 less than her brother ben. Ben spends $550 and Amy gets $750.
Assume that the money with Ben and Amy after transactions is $x and $y respectively. Let Ben has a initial amount of $m and Amy has of $n.
n = m - 1275
After transactions -
x = m - 550
y = m - 1275 + 750 = m - 525
Now -
m - 525 > m - 550 for every value of [m].
So, now Amy has more money.
Therefore, Amy has more money than her brother after all transactions.

The length of a rectangle is 5 in longer than its width.
If the perimeter of the rectangle is 74 in, find its length and width.
Answer:
Length = 21
Width = 16
Step-by-step explanation:
We know that the formula for perimeter is:
P=2W+2L
And we also know that:
L=W+5
So then we put all that we know in the formula:
74=2W+2(W+5)
Now we expand the brackets and do some algebra:
74=4W+10 (-10)
64=4W (÷4)
16=W
Now that we know the width we can pop that into the length equation:
L=16+5
L=21

Answer:
11/15
Step-by-step explanation:
Answer:
- 11 / 15
Step-by-step explanation:
x = - 2
y = - 1 / 5
1 / 3 + x . z
= 1 / 3 + ( - 2 ) . ( - 1 / 5 )
= 1 / 3 + ( - 2 . - 1 ) / 5
= 1 / 3 + 2 / 5
1 / 3
= ( 1 / 3 ) x ( 5 / 5 )
= ( 1 x 5 ) / ( 3 x 5 )
= 5 / 15
2 / 5
= ( 2 / 5 ) x ( 3 / 3 )
= ( 2 x 3 ) / ( 5 x 3 )
= 6 / 15
1 / 3 + 2 / 5
= 5 / 15 + 6 / 15
= ( 5 + 6 ) / 15
= 11 / 15

Answer:
1/3
Step-by-step explanation:
1. When we divide any x-input by the y-input, we get 3. This is the same as multiplying the x-input by 1/3 to get the y-input. Let's see if it works!
[tex]3 * \frac{1}{3} = \frac{3}{3} = 1[/tex] [tex]6 * \frac{1}{3} = \frac{6}{3} = 2[/tex] [tex]12 * \frac{1}{3}= \frac{12}{3}=4[/tex] [tex]15*\frac{1}{3}=\frac{15}{3} =5[/tex]2. Great! All our x-inputs and y-inputs match up, meaning the constant of proportionality, k, is 1/3.
