Answer:
x = 17
Step-by-step explanation:
The angles 3x + 1 and 4 + 2x MUST total 90 degrees:
5x + 5 = 90 degrees
or: 5x = 85 degrees
therefore: x = 17
Answer:
x=17
Step-by-step explanation:
(3x+1)+(4+2x)=90
3x+1+4+2x=90
5x+5=90
5x + 5 - 5 = 90 - 5
5x = 85
5x/5 = 85/5
x = 17

In science class, Jada uses a graduated cylinder with water in it to measure the volume of some marbles. After dropping in 4 marbles so they are all underwater, the water in the cylinder is at a height of 10 milliliters. After dropping in 6 marbles so they are all underwater, the water in the cylinder is at a height of 11 milliliters.
What is the volume of 1 marble?
How much water was in the cylinder before any marbles were dropped in?
What should be the height of the water after 13 marbles are dropped in?
Is the volume of water a linear relationship with the number of marbles dropped in the graduated cylinder? If so, what does the slope of the line mean? If not, explain your reasoning.
Answers
0.5

Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.
How many days will it take Amir to catch up to Jesse, and how many pages will they each have read?
1. Write an equation to represent the number of pages Amir has read. Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.
2. Write an equation to represent the number of pages Jesse has read.
Using x, the number of days Amir has been reading, write an expression to represent the number of days Jesse has been reading. Remember that Jesse started reading one day before Amir. Use this expression to write an equation for the number of pages Jesse has read. Let y represent the number of pages read.
3. Write the system of equations using your answers from questions 1 and 2.
4. You will use substitution to solve this system. Which variable will you substitute for and why? Show the equation that results from the substitution.
5. Solve the system of equations. Show your work.
Answers
Answer:
6 days
210 pages
Step-by-step explanation:
As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.
Now since he reads 35 pages per day.
210 Pages
STEP-BY-STEP:
Amir has been reading X and the pages is Y
Now since he reads 35 pages per day
mathematically it's: y = 35x
For Jesse, he started to read a day before:
Days he read would be x + 1.
Since he reads 30 per day the total number of pages is
30(x+1)
So it's y = 30(x+1)
Now The Work:
35x = 30(x+1)
35x = 30x + 30
35x -30x = 30
5x = 30
x = 30/5
x = 6 Days
It will take Amir 6 days to catch to Jesse
35 * 6 or 30(6+1) = 210

Answer: 20 cm ^2 (20 cm squared)
Step-by-step explanation:
This is a rectangular prism so Volume = Length(Width)(Height)
You only know the height and Volume so you do :
60 = L(W)(3) :then bring the 3 over:
60/3 = L(W)
20 = L(W)
Since area = L(W)

There are two angles m∠14 and m∠13 which are supplementary to angle 14.
AngleAngle is formed by the intersection of two lines. Two angles are said to be supplementary if both of the angles add up to 180 degrees.
From the diagram:
m∠13 + m∠14 = 180° (sum of angles in a straight line )
Also:
m∠15 + m∠14 = 180° (sum of angles in a straight line )
There are two angles m∠14 and m∠13 which are supplementary to angle 14.

Answer: w = -3/2u + 2
Step-by-step explanation: The independent variable, normally x, is not impacted by other variables. The problem is asking you to put the equation in w= form. W is the dependent variable while u is the independent variable (we’re used to seeing y= form, where x is independent and y is dependent. This is the same thing with different letters).
-12u + 13 = 8w - 3
-12u + 16 = 8w (add 3 to both sides)
(-12u + 16)/8 = w (divide both sides by 8)
-12/8u + 16/8 = w
-3/2u + 2 = w (simplify)
Answer: w = -3/2u + 2
