Answer:
x = 6.5
Step-by-step explanation:
5(x−2)+3x−4= 38
5 times x, 5 times -2 =
5x - 10 + 3x - 4 = 38
Combine like terms
5x + 3x = 8x
8x - 10 - 4 = 38
Add 10
8x -10 +10 -4 = 38 +10 =
8x -4 = 48
Add 4
8x -4 +4 = 48 +4
8x = 52
Divide by 8
8x/8 = 52/8 =
x = 6.5
Which expression can represent 70% of x?
3 (StartFraction x Over 4 EndFraction) minus one-half (StartFraction x Over 10 EndFraction)
3 (StartFraction x Over 4 EndFraction) minus (StartFraction x Over 10 EndFraction)
(StartFraction x Over 2 EndFraction) + (StartFraction x Over 10 EndFraction)
(StartFraction x Over 2 EndFraction) + one-half (StartFraction x Over 4 EndFraction)
NVM THE ANSWER WAS
3 (StartFraction x Over 4 EndFraction) minus one-half (StartFraction x Over 10 EndFraction)
Answer:
The answer is Dun Dun Duuun 3 {x/4} - 1/2{x/10}
The expression equivalent to 70% of x is,
⇒ 3 (StartFraction x Over 4 EndFraction) minus one-half (StartFraction x Over 10 EndFraction)
⇒ 3 (x/4) - 1/2 (x/10)
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
The expression is,
⇒ 70% of x
Now, We an simplify the expression as;
⇒ 70% of x
⇒ 70/100 × x
⇒ 70x/100
⇒ 7x/10
By option 1;
⇒ 3 (x/4) - 1/2 (x/10)
⇒ 3x/4 - x/20
⇒ (60x - 4x) / 80
⇒ 56x / 80
⇒ 7x/10

Find the coordinates of H if X(-8, 4) is the midpoint of GH and G(2, -9).
Step-by-step explanation:
Hey there!
The given midpoint is; X(-8,4) and G(2,-9).
To find: H
Now; You need to use formula for midpoint.
[tex]midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]
Put all values.
[tex]( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )[/tex]
As they are equal, their corresponding elements are equal.
[tex] - 8 = \frac{2 + x}{2} [/tex]
[tex] - 16 - 2 = x[/tex]
x = -18
[tex]4 = \frac{ - 9 + y}{2} [/tex]
[tex]4 \times 2 = - 9 + y[/tex]
[tex]8 + 9 = y[/tex]
[tex]y = 17[/tex]
Therefore, y = 17.
Therefore, H =( -18,17).
Hope it helps....
Answer:
(-18, 17)Step-by-step explanation:
Given Line segment GH with midpoint X(-8, 4) and G(2, -9)To findCoordinates of H(x, y)SolutionUsing midpoint formula
(2 + x)/2 = -8 ⇒ x + 2 = -16 ⇒ x = -18(-9 + y)/2 = 4 ⇒ y - 9 = 8 ⇒ y = 17So the coordinates of H are

Answer:
GCF is Greatest Common Factor.
Explaination:
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
12 out of 15 students play in the school band. In a class of 45 students, how many do NOT play in the band?
Answer: 36
12 out of 15 people play in the school band. In the class, 36 do not play.
12:15 is equal to a ration of 36:45.
So, it is the answer. 36 out of 45 people in the class play in the band.
Hope this helps!
Answer:
9 I think
Step-by-step explanation:
I wanted to simplify 12 out of 15 and I did by dividing 3 out of both of them which would now equal 4 out of 5. I know that 4 out of 5 is 80%. so, I did 80 % of 45 which equals 36 which means 36 people were in band. So now you minus 36 from 45 which is 9
9 people did not play in band

graph a line with a slope of -5 that contains the point (-3, -4)
Answer:
y = -5x-19
Step-by-step explanation:
Use the point-slope formula to plug in the x1 and y1 and the slope -5 to get the equation y = -5x-19.
Formula: y-y1 = m(x-x1)
m = slope
x1 = x-value
y1 = y-value
Answer:
y=-5x-15
Step-by-step explanation:
starts off in point-slope form:
y+4=-5(x+3)
distribute the 5:
y+4=-5x-15
subtract 4 from each side:
y=-5x-20

Explanation:
Replace every x with -3
Then use the order of operations (PEMDAS) to simplify
y = -2x^2 + x - 5
y = -2(-3)^2 + (-3) - 5 ... x replaced with -3
y = -2(9) - 3 - 5
y = -18 - 3 - 5
y = -21 - 5
y = -26
Answer:
-26
Step-by-step explanation:
1. plug in -3 for all x's
-2(-3)^2 + (-3) -5
2. combine like terms
-2(-3)^2 - 8
3. pEmdas. deal with exponent first (remember: only affect the 3, since it's in parentheses! also when you square a negative number, it becomes positive!)
-2(9) - 8
4. peMdas. multiply -2 and 9 next.
-18 - 8
5. pemdaS. subtract 8 from -18.
-18 - 8 = -26
Solve the equations 7(2x+6)=1
Answer:
Step-by-step explanation:
B
Answer:
x = - [tex]\frac{41}{14}[/tex]
Step-by-step explanation:
Given
7(2x + 6) = 1 ← distribute parenthesis on left side
14x + 42 = 1 ( subtract 42 from both sides )
14x = - 41 ( divide both sides by 14 )
x = - [tex]\frac{41}{14}[/tex]
