Solve 7+2x over 3 = 5
Please and thank you! x
Answer:
x = 4
Step-by-step explanation:
(7 + 2x) / 3 = 5
Cross product
7 + 2x = 5 * 3
7 + 2x = 15
Subtract 7 from both sides
2x = 15 - 7
2x = 8
Divide both sides by 2
x = 8/2
x = 4
y=x+4
2x+3y=17

Answer:
( 1, 5 )
x = 1
y = 1
Step-by-step explanation:
y = x + 4
2x + 3y = 17
Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.
2x + 3y = 17
2x + 3 ( x + 4 ) = 17
Distributive Property
2x + 3 * x + 3 * 4 = 17
2x + 3x + 12 = 17
Combine Like Terms ( 2x and 3x)
5x + 12 = 17
Subtract 12 on both sides of the equation
5x + 12 - 12 = 17 - 12
5x = 5
Divide by 5 on both sides to isolate the variable
5x/5 = 5/5
x = 1
Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"
y = x + 4
y = 1 + 4
y = 5
x = 1
y = 5
( x, y )

I rlly need help and the operation bby plssssss help me
Answer:
∠ AFE = 35°
Step-by-step explanation:
∠ EFD = ∠ BFC = 55° ( vertically opposite angles )
Since BD is a straight line , then
∠ EFD + ∠ AFE + AFB = 180°, that is
55° + ∠ AFE + 90° = 180
∠ AFE + 145° = 180° ( subtract 145° from both sides )
∠ AFE = 35°

A full glass of water can hold 1/6 of a bottle.
How many glasses of water can be filled with 3 1/2. bottles of water?
Answer:
21 glasses
Step-by-step explanation:
6 glasses in a bottle
3 x 6 = 18
3 glasses in half a bottle
18 + 3 = 21
Answer:
21 glasses
Step-by-step explanation:
let 'g' = glasses of water
create a proportion, glasses over bottles equals glasses over bottles
1 = g
1/6 7/2
cross-multiply: 1/6g = 7/2
cross-multiply: 2g = 42
g = 21

Given a quadratic equation px^2 + 8x + 2 does not have real roots. Determine the range of the values of p.
[4 marks]
Step-by-step explanation:
For a quadratic equation to have no real roots, the discriminant b² - 4ac must be negative.
For px² + 8x + 2 = 0,
We have a = p, b = 8 and c = 2.
=> (8)² - 4(p)(2) < 0
=> 64 - 8p < 0
=> 8p > 64
=> p > 8
Hence the range for p is p > 8.

Answer:
The equation of the line is:
y = 3xStep-by-step explanation:
Given the table
x y
0 0
1 3
2 6
3 9
4 12
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptTaking the two points from the table
(1, 3)(2, 6)Determining the slope between (1, 3) and (2, 6)
(x₁, y₁) = (1, 3)
(x₂, y₂) = (2, 6)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [6 - 3] / [2 - 1]
= 3 / 1
= 3
Thus, the slope of the line = m = 3
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the table, it is clear
at x = 0, y = 0
Thus, the y-intercept b = 0
now substituting m = 3 and b = 0 in the slope-intercept form of the line equation
y = mx + b
y = 3x + 0
y = 3x
Therefore, the equation of the line is:
y = 3xThe graph of the line equation y = 3x is also attached.

Mr Lee has a family of 6 people and Mrs Scarlett has a family of 4. They were given 15 kg of chocolate
when they visited a chocolate factory for work. If they decide to share it so that each family
member gets an equal amount, determine the required ratio and hence calculate how much
chocolate Mr Lee and Mrs Scarlett will each take home to their families.
Answer:
Mr Lee gets 9kg
Mrs Scarlett gets 6kg
Step-by-step explanation:
First, we have 15kg of chocolate and a total of 6 + 4 = 10 people.
We want to divide the 15kg of chocolate evenly between these 10 people, then we just need to do the quotient
15kg/10 = 1.5kg
This means that each person gets 1.5 kg of chocolate.
Now, Mr. Lee has a family of 6 people, and each one of these 6 people got 1.5 kg of chocolate, then the total amount of chocolate that Mr. Lee will bring home is 6 times 1.5kg:
6*1.5kg = 9kg
And Mrs Scarlett will get the remaining, that is:
15kg - 9kg = 6kg
Mrs Scarlett will get 6kg of chocolate.
