solve for x: 4x + 9 = 2x - 7
Answer:
-8
Step-by-step explanation:trust me
Answer:
x=8
Step-by-step explanation:
4x+9=2x-7 (subtract both of the numbers with variables)
4x
-2x
2x=+9-7
-9 -9 (-9-7=16) +* 2 negatives cancels out to make a positive *+
2x=16
16/2=
x=8

Scientists are able to make observations and inferences about what is below the crust of Earth by using scientific evidence. Which of these are examples of evidence that scientists use to discover what the layers of Earth’s crust are like? Choose the two that apply.
Answer:
Step-by-step explanation:
Answer: seismic waves & samples of rock
Explanation: Scientists record the seismic waves caused from the waveforms of different earthquakes to infer the structures below the crust of the Earth. They record these seismic waves through seismographs from a machine called the seismometer. Scientists also observe the samples of broken rock that they get from the destruction multiple different earthquakes to make comparisons and studies to provide us details of what the bottom of Earth’s crust looks like.

In order to solve for the variable in the equation 2 (x + 3) + 5 x = 3 (2 x minus 1), Jaleesa begins by applying the distributive property, then combines like terms. Which equation is the result of these steps?
7 x + 6 = 6 x minus 3
2 x + 6 + 5 x = 6 x minus 3
2 x + 3 + 5 x = 6 x minus 1
7 x + 3 = 6 x minus 1
Answer:
7x + 6 = 6x - 3
Step-by-step explanation:
2(x+3) + 5x = 3(2x-1)
Distribute
2x + 6 + 5x = 6x - 3
Combine like terms
7x + 6 = 6x - 3
hope this helps

Part 1: How's the weather?
Investigate the weather forecast in your city.
Record the high and low temperatures that are forecast for the next 7 days in the table below. In the columns titled, Difference," record the change in temperature from the day before. To do this, subtract the previous temperature from the current temperature Be sure to use positive and negative numbers as needed! For example, if yesterday’s temperature was 70 and today’s temperature was 65, the difference is 65 – 70 = -5.
Date
High Temperature
Subtract the previous temperature from current temperature
Difference
Low Temperature
Subtract the previous temperature from current temperature
Difference
1 -N/A- -N/A- -N/A- -N/A-
2
3
4
5
6
7 Note: The columns for Day One's subtraction and difference cannot be filled in. As this is the first data point, there is no previous temperature to subtract.
Write a mathematical expression using the information from your table to answer the following questions:
What is the mean change in the forecasted high temperatures? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.
What is the mean change in the forecasted low temperatures? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.
Answer:
What explains the difference in temperatures between the two cities?
Step-by-step explanation:
Answer: Using the mean concept, it is found that:
1. The mean change in the forecasted high temperatures is of -0.33ºC.
2. The mean change in the forecasted low temperatures is of 0.5ºC.
-----------------------------
The mean of data-set is given by the sum of all observations divided by the number of observations.
Item 1:
The changes in the high temperature are: 2, 1, -1, -1, -1, -2
Thus:
The mean change in the forecasted high temperatures is of -0.33ºC.
Item 2:
The changes in the low temperature are: 2, -2, 2, 1, 0, 0.
The mean change in the forecasted low temperatures is of 0.5ºC.

Caiden earned $475 from mowing lawns last summer. He deposited this money in an account that pays an interest rate of 3.8%. What will be the amount of interest earned after 15 years
Answer:
The balance after 15 year is $831.25 .
Step-by-step explanation:
Formula
Where P is the principle and r is the rate of interest in the decimal form and t is the time.
As given
Caiden earned $475 from mowing lawns last summer.
He deposited this money in an account that pays an interest rate of 3.8% compounded annually.
Here
P = $475
3.8% is written in the decimal form.
= 0.038
r = 0.038
t = 15 years
Put in the formula
Amount = $831.25
Therefore the balance after 15 year is $831.25 .
What is the value of the expression m8−(34−n) in simplest form, when m = 6 and n = 18?
please hurry
Answer:
N is just simply 18
so 6*8-(34-18) and use pemdas to solve
34-18=16
6*8-16
48-16
32
so the value is 32
The value of the expression for m = 6 and n = 18 is 16,79,600.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the expression as -
m⁸ - (34 - n)
The expression given is -
m⁸ - (34 - n)
Now, for m = 6 and n = 18, we can write -
6⁸ - 34 + 18
6⁸ - 16
(6 x 6) x (6 x 6) x (6 x 6) x (6 x 6) - (16)
36 x 36 x 36 x 36 - 16
16,79,616 - 16
16,79,600
Therefore, the value of the expression for m = 6 and n = 18 is 16,79,600.
