Answer:
1a) x = -41
1b) x = -1
1c) x = 29/3, or x = 9.66 in decimal form
1d) x = -4
----------------
2a) y = -3
2b) y = -60
2c) y = -83
2d) y = -50
Step-by-step explanation:
1a) y = x + 11
-30 = x + 11
-11 -11
------------------
-41 = x
1b) y = -2x - 32
-30 = -2x - 32
+32 +32
----------------------
2 = -2x
/-2 /-2
----------------------
-1 = x
1c) y = -3x - 1
-30 = -3x - 1
+1 +1
-----------------
-29 = -3x
/-3 /-3
------------------
29/3 = x
9.66 = x
1d) y = 5x - 10
-30 = 5x - 10
+10 +10
----------------------
-20 = 5x
/5 /5
----------------------
-4 = x
------------------------
2a) y = x + 3
y = -6 + 3
y = -3
2b) y = -2x - 72
y = -2(-6) - 72
y = 12 - 72
y = -60
2c) y = 3x - 65
y = 3(-6) - 65
y = -18 - 65
y = -83
2d) y = 4x - 26
y = 4(-6) - 26
y = -24 - 26
y = -50
Which of the following equations is equivalent to
Answer:
Step-by-step explanation:
[tex]\frac{x+3}{3} =5- \frac{x-3}{6} \\(\frac{x+3}{3}) *6 =5 - (x-3)[/tex]
[tex]2x+6 = 5 - x+3[/tex]
Answer:
none
Step-by-step explanation:
We can start by multiplying both side of the equation by 6 in order to remove the fractions.
[tex]6*\frac{x+3}{3} = 6(5 - \frac{x-3}{6})[/tex]
[tex]2(x + 3) = 30 - 6*\frac{x-3}{6}[/tex]
[tex]2x + 6 = 30 -(x - 3)[/tex]
[tex]2x + 6 = 30 - x + 3[/tex]
Now, we can try to see if this equation is equivalent to the other options.
Every option has the left side as 2x - 6. In order to get that, we need to subtract 12 on both sides:
[tex]2x - 6 = 30 - x + 3 - 12[/tex]
This simplifies to
[tex]2x-6 = 18 - x + 3[/tex]
This is not the same as any of the options shown.
We can check this by solving the equations.
2x - 6 = 18 - x + 3
3x = 6 + 18 + 3
3x = 27
x = 9
Now, the first option:
2x - 6 = 10 - x - 3
3x = 6 + 10 - 3
3x = 13
x = 13/3
The second option is the exact same as the third, so they would have the same solution:
2x - 6 = 30 - x- 3
3x = 6 + 30 - 3
3x= 33
x = 11
Since none of the options have the answer 9, they are not equivalent to the equation shown.
Select all ratios equivalent to 20:5.
The answer is : 40:10
*multiply by 2
If helpful, brainliest please !
Answer:
40:10 & 8:2
Step-by-step explanation:
20 * 2 = 40
5 * 2 = 10
8 * 2.5 = 20
2 * 2.5 = 5
2:1 does not work because only 2 * 10 = 20, but 1 *10 = 10 and there is no 10. There is only 5.

A number has many factors including 3 and 8. What other number must also be a factor of the same number?
Two "factors" are multiplies together to product another number (the product). So, for example, the prime factors of 10 are 2 and 5. Prime factors that, themselves, have only factors of 1 and themselves. Non-prime numbers, like 10, have prime factors. Note that 1 is a factor of all integers.
If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."
Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).
Practice:
What is the square root of 49?
What is the square root of 100?
What is the square root of 625?
Memorize the squares of the numbers from 1 to 10, or 1 to 20 -- that will be very helpful in math classes.

Violet has 30 glass tiles. she would like to mosaic tile a tabletop with 10 times that number of tiles. how many tiles does violet want to use?
If you can help, please respond! Tysm! <3
Violet will need to use 300 tiles for tabletop.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Number of glass tiles Violet has = 30
Now,she would like to mosaic tile a tabletop with 10 times that number of tiles
So, number of tiles become = 10 times Number of glass tiles Violet has
⇒ number of tiles become = 10*30
⇒ number of tiles become = 300 tiles
Thus, Violet will need to use 300 tiles for tabletop.

Jordan has to solve this division problem: 42 divided by 7 = ?
Which of the following equations can he use?
42 + 7 = ?
7 x 42 = ?
? x 7 = 42
7 divided by 42 = ?
The correct equation that Jordan can use to solve the division problem 42 divided by 7 is:
? x 7 = 42
So, the correct equation is option 3) ? x 7 = 42.
Given that, Jordan has to solve this division problem: 42 divided by 7 = ?
In this case, Jordan needs to find the value of the missing factor, which represents how many times 7 can be multiplied to get 42.
Therefore, he can use the equation:
? x 7 = 42
This equation represents the inverse operation of division, which is multiplication.
When we know one factor (7) and the product (42), we can use multiplication to find the missing factor (the quotient).
By solving for the missing factor, he will find the correct answer to the division problem:
The missing factor = 42 / 7 = 6
So, the correct equation is option 3) ? x 7 = 42.
