Answer:
-6.5
Step-by-step explanation:
-2 + -9 =-11 ÷2=-6.5
Answer:
Depends. If you were asking 2+-9/2, according to the rules of PEMDAS it would be -2.5 but by the way you wrote that, I'm assuming you meant (2+-9)/2 which is -3.5.

What is the surface area of the cylinder with height 5 yd and radius 7 yd?
Answer:
168*pi square yards.
Step-by-step explanation:
So, first the surface area of a cylinder is the sum of the two circles plus the rectangle forming the column.
The area of the column is the height x perimeter of the circle
and
The area of the circles is pi x radius^2
Just add all of those up.
Column: 5 * 2 * pi * 7 = height * 2pi * radius = 70*pi
2 x Circle = 2 x pi * 7^2 = 2x49*pi = 98*pi
Sum: 70*pi + 98*pi = 168* pi

Is (-10, 10) a solution to this system of equations?
18x + 20y = 20
20x – 2y = 9
yes
no
Answer:
No
(The first system is correct but the second one is wrong)
Step-by-step explanation:
You can plug (-10,10) into these equations
a) 18(-10)+20(10)=20
-180+200=20
20=20
b) 20(-10)-2(10)=9
-200-20≠9
-220≠9

jenny goes to the shop she buys
. three cups for £1.24 each
.three saucers for 95p each
. a teapot for £6.18
jenny has £20 to spend she also wants to but some plates, which are £1.57 each.
what is the greatest number of plates jenny she can buy
Answer:
5
Step-by-step explanation:
1.24 times 3 = 3.72
.95 (the value of pence to a pound in decimal form) = 2.85
6.18 for the teapot
2.72+2.85+6.18=11.75
She now has £8.25 left (20-11.75).
8.25/1.57=the amount of plates she can buy: 5.25477707006, so 5 with some money left

Answer:
Steps: 1) Isolate the absolute value on the LEFT Side of the equation ... 12) A recent poll suggests that 47% of American citizens are going to vote for the ... margin of error of £4.5%. Set up and solve an absolute value inequality to determine the range of possible ... determine if the Democratic candidate will win the election?
Step-by-step explanation:
The percentages candidate could earn falls in the range of absolute value inequality |47 - x| ≤ 4.5.
What is Absolute Value Inequality?Absolute value inequalities are kind of inequality expressions which includes the absolute value symbol in the expression.
For example : |x - 5| < 4 is an absolute value inequality.
Given that,
Percentage of American citizens going to vote for candidate B = 47%
Tolerance level = 4.5%
Suppose x be the percent of voters who will vote for candidate B.
Value of x can be,
47% + 4.5% = 51.5%
Or,
47% - 4.5% = 42.5%
The absolute value inequality for the situation is,
|47 - x| ≤ 4.5
Hence the absolute value inequality is |47 - x| ≤ 4.5.

Describe the slope of the line
Find the slope.
m =
Answer:
m = -3/5
Step-by-step explanation:
Since the line is going downwards towards the right, it is a negative slope.
We can use the points to solve for the slope.
m = -2 - 1 / 2 - (-3)
m = -2 - 1 / 2 + 3
m = -3/5
Therefore, the slope is -3/5.
