Answer:1. x=11
Step-by-step explanation:
For the rest of the questions to do inverse operation! it says x+7=18.... ask yourself 7 plus what give me 18 use a calculator or paper subtract 18 from 7 and it gives you your answer which is 11.
For the ones like number 4. You do the same thing but instead of subtracting you add 6+3 it will give you 9 and to make sure sure add the numbers together. what ever number you get you plug the number into your equation and the statement should be true.
Help is needed please and thank you

Answer: Mean Absolute Deviation Calculator
Instructions
This calculator computes the mean absolute deviation from a data set:
You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".
What is the mean absolute deviation
The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.
Mean absolute deviation formula
This calculator uses the following formula for calculating the mean absolute deviation:
$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$
where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

Answer:
option a
Step-by-step explanation:
as 145 +10 = 155°
and total angle measure of triangle is 180
so
180-155 = 25°
in option a one angle is 10
other is 25 so obviously last angle will be 145
and same is in the triangle abc
one angle is 10 other is 145 and last is 25
both hve same measures thus are same triangles.

Please help I’m confused math is hard!
Answer:
Step-by-step explanation:
basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.
first, you need to factor out the equation.
start with the original equation.
V=4x^3+10x^2+4x
factored form:
V= 2x(2x^2+5x+2)
next, you're going to want to plug in the values.
the answer asks for x=4, but you should do both.
v=2(3)(2(3)^2+5(3)+2)
do not forget to do the exponents before!
v=6(18+15+2)
v=6(35)
v=210 ft^2
that's the answer for if x was equal to 3.
V= 2x(2x^2+5x+2)
don't forget to write the original equation first.
V=2(4)(2(4)^2+5(4)+2)
V=8(36+20+2)
V=464 ft^2⬆is your answer! hope this helped!!

A scale measures a 1,000 gram weight as 945 grams. What is the percent error?
Answer:
5.5%

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?
Answer:
$8,900
Step-by-step explanation:
You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.
Here i = $8,000*0.075*1.5 (representing 18 months)
i + $900
At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.
