Answer:
3x-x+2=4
Step-by-step explanation:
You replace y in the problem with 5 so you have 4x+3*5=8 then you multiply 3*5 and 15 then rewrite your problem so it looks like 4x+15=8 then add 15 to the side with the 8 so it looks like 4x=23 then divide 23 by 4 and you get x.
Answer:
y = 3/4x + 5
-3x + 4y = 20
Step-by-step explanation:
In order to write this equation, you need the slope and y-intercept (I'll answer in slope-intercept form and standard form)
First change that standard form equation to slope-intercept form:
1. 4x + 3y = 8
2. 3y = -4x + 8
3. y = -4/3x + 8/3
Step 1 is given.
In step 2, 4x was subtracted from both sides.
In step 3, both sides were divided by 3.
Slope-intercept form:
y = mx + b
m is the slope and b is the y-intercept.
m = 3/4; the slope of a line perpendicular to another line is the negative reciprocal of the other line's slope (ex: line's slope is 1/4; a line perpendicular to it has a slope of -4, the negative reciprocal)
b = 5; the y-intercept was stated in the problem
Now, you put it together: y = 3/4x + 5
Standard form:
You can just change the slope intercept form back into standard form by moving the numbers around a bit:
1. y = 3/4x + 5
2. -3/4x + y = 5
3. -3x + 4y = 20
Step 1 is given.
In step 2, 3/4x was subtracted from both sides of the equation.
In step 3, both sides were multiplied by 4 so that the equation could have nice whole numbers. (this step is optional, I just think it's easier to read this way)
Helpp please 100 points
Answer:
z=7 and x=60
Step-by-step explanation:
well from the square that is combining the angles 1 and 2, they tell you that that is a right angle and you know that angle 2 is 38 so 90-38=52 which is the measurement of angle 1 so to find z, you would have to divide 38/-2 which is -19 and then add 12 so 12-19=-7 so z=7. so you know that one side =90 degrees so angle 3 must also =90 degrees because they are on the same line and a line is equal to 180, so all you have to do is reverse the operations in 1 1/2x to find x, so 1 1/2 or 3/2 divided by 90 is 60.
pls this took a lot of work and i kindly ask for brainliest.
Use the order of operations to evaluate.
Answer:
185.8-(25+1)*3
185.8-26*3
answer: 107.8
Answer:
We know what all of these signs mean, but what does 5^2 mean? I'll show you.
5^2, more commonly known as 5 squared, means a number times itself.
With that given info, we can multiply 5 times itself and find the answer.
[tex]5 * 5 = 25[/tex]
Put 25 in the blank.
Now you know what to do.
Incase you have more questions, I can answer them with PEMDAS.
Parentheses always come first
Exponents before variables

Determine the length of the unknown side of the right triangle. If it is not an exact answer, what integer is it closest to? (Don't forget to include units!)
Answer:
12in
Step-by-step explanation:
15in squared - 9in squared is 144in and the square root of 144 is 12
Answer:
12 in
Step-by-step explanation:
Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
let x = unknown side
Given:
a = xb = 9c = 15Substituting the given values into the equation:
⇒ x² + 9² = 15²
⇒ x² + 81 = 225
⇒ x² + 81 - 81 = 225 - 81
⇒ x² = 144
⇒ x = √(144)
⇒ x = ±12
As the length is positive, x = 12 only.
Therefore, the length of the unknown side is 12 in.

Explain how to translate the statement into an equation. Use n for the variable.
Sixty-three is the product of nine and a number
The equation will be 63=9*n.
We have to first start with what is given,
The given statement is Sixty-three is the product of nine and a number, an equation generally contains both some constants and variables. Here in the given question we have to identify the constants and the variables, the constant as we can see is Sixty three and the number with which we have a product is also a constant that is nine.
Now the unknown variable is the one with which nine is multiplied, generally in mathematics we represent unknown by n so hence the final equation becomes 63 = 9*n.

Can somebody please solve this? It's a coordinate thingy
Answer:
Coordinates involve two points. (x,y)
Too find a pair (coordinate), use the x and y lines on the graph and see where the point falls.
For example
Point A is number 1 on the y axis
number -4 on the x axis
So, you would write the coordinate out at
(-4,1)
The y axis values are the second point, so after you plot all of letters, use the y axis numbers and number them from least to greatest so you can find the mystery word.
1. The question is in the picture. Please help :D
Answer:
They would be 5%
Step-by-step explanation not for sure but what I did was add the correct numbers and added the incorrect numbers and It came out to 110 and 105 so I used 110/105 and looked at how much the percentage was and then when I got that I just took the percentage that would make it 100 percent. Hope it helps and sorry if it is incorrect I tried.

3 - 1 = 2
What is the measure of 1 if 1 is (2x - 3) and 2 is (8x)?
Step-by-step explanation:
(2x - 3) + 8x = 180 (linear pairs)
10x - 3 = 180
10x = 180 + 3
10x = 183
x = 183÷10
x = 18.3
1 = 2x - 3
2 × 18.3 - 3
= 33.6
2 = 8x
8 × 18.3
146.4
Angle 1 + Angle 2 = 180
33.6. + 146.4. = 180

please help! I'm not good at this math and I really need some help. If someone could explain it or just say the answer, anything is helpful! Here's a picture of the question:
Answer:
32, 52, 96
Step-by-step explanation:
add all the angles together
x + (2x - 12) + 3x
= 6x - 12
all angles in a triangle add to 180 so
6x - 12 = 180
add twelve on both sides to get rid of it
6x = 192
divide both sides by 6x
x = 32
now substitute
x = 32
2x - 12 = (32 x 2) - 12 = 52
3x = 32 x 3 = 96
In the diagram, the measures of ∠1, ∠4, and ∠5 are 120°. The measure of ∠7 is 60°. Are lines c and d parallel
Answer:
yes
Step-by-step explanation:
both lunes c and d are parrallel
line c =
∠1 + ∠4 = 240°
360 -240= 120 °
120/2 = 60°
as angle 2 and 3 are opposite each other they will have the same angle { 60°}
line d =
∠5 is 120° , ∠5 and ∠8 are opposites so ∠8 is equal to 120°
120 ×2 = 240
360-240=120°
120° / 2 = 60°
so ∠7 and ∠6 are 60°
both lines are parallel as the angles are corresponding

Subtract 2 from each side
3x+2-2 =11-2
3x = 9
Divide by 3
3x/3 =9/3
x = 3
Answer:
x=3

4x + 2 = x + 11
subtract 2 and x from both sides
3x = 9
divide by 3 on both sides
x = 3
