1. For the equation, x-7 = 24. can a value be substituted for x to make that a true
number sentence? How many values could be substituted for x and have a true
number sentence?
Answer:
The value 31 can be substituted for x. Only the value 31 can be substituted.
Step-by-step explanation:
So to solve a one step equation the goal is to isolate the variable. As you can tell from we are subtracting the 7. The opposite of addition is subtraction so we want to add the 7. -7 plus a positive 7 is 0 which cancels it out. Now we have x=24. However what you do to one side you need to do to the other. So we add 7 to the 24. 7+24 is 31. Therefore 31 can be substituted for x. Lets check out answer. What is 31-7? 31-7 is 24. Now we know our work was correct
Write the following equations in slope intercept form
Equation 1: y-7x=6
Equation 2: y+7x=8
Answer:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8
Step-by-step explanation:
Isolate the y variables in both equations
Equation 1:
y - 7x = 6
y = 7x + 6
Equation 2:
y + 7x = 8
y = -7x + 8
So, the equations in slope intercept form are:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8

Step-by-step explanation:
A factor of n is a number which when multiplied by another number gives us the number n. The expression that can not be simplified is √38.
What is a factor?A factor of n is a number which when multiplied by another number gives us the number n.
The given expression can be simplified as shown below.
√24 = √(3×2×2×2) = 2√6√32 = √(2×2×2×2×2) = 4√2√27 = √(3×3×3) = 3√3√38 = √(2×19), since there are no common factors, therefore, √38 can not be simplified.Hence, the expression that can not be simplified is √38.

Solve the literal equation 2a - b = 3b – a for a .
help pls
Answer:
a = 4/3 b
Step-by-step explanation:
2a - b = 3b – a
Add a to each side
2a+a - b = 3b – a+a
3a -b = 3b
Add b to each side
3a -b+b = 3b+b
3a = 4b
Divide each side by 3
3a/3 = 4b/3
a = 4/3 b
Answer:
a = 4/3 b
Step-by-step explanation:
2a - b = 3b – a
Add a to each side
2a+a - b = 3b – a+a
3a -b = 3b
Add b to each side
3a -b+b = 3b+b
3a = 4b
Divide each side by 3
3a/3 = 4b/3
a = 4/3 b

Answer:
105°
Step-by-step explanation:
m(15) = 75°
Also it's given that m||n . So taking y as transversal ,
m(15) = m(13) = 75°
Also it's given that x||y . So taking m as transversal ,
m(13) = m(5) = 75°
Now m(5) & m(1) are linear pair. So ,
m(5) + m(1) = 180°
=> 75° + m(1) = 180°
=> m(1) = 180° - 75°
= 105°

Find the following lengths.
X=_____
BC=10
Answer:
see explanation
Step-by-step explanation:
Since B is the midpoint of AC, then
AB = BC , substitute values
3x - 5 = x + 5 ( subtract x from both sides )
2x - 5 - 5 ( add 5 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Thus
BC = x + 5 = 5 + 5 = 10
