2(h -3.5) = -11
what is h?
Answer: -2
Step-by-step explanation:
2(h -3.5) = -11 Distributive property
2h - 7 = -11. Add 7 to both sides
2h = -4. Divide both sides by 2
h = -2
Answer: The answer is -2 :)
Step-by-step explanation: 2(h -3.5) = -11 distributive propert
2h-7=-11 Add -7 to both side
+7 =+7
2h=-4 Divide 2 to both side
2 = 2
h=-2

System of Equations : Money
Damian has been saving coins he finds on the ground for several months. So far he has found 37 coins that are either pennies or nickels. The combined value of his found pennies and nickels currently is $1.09. What is the system of linear equations, written using standard form, represents the situation if Damian found p pennies and n nickels.
Answer:
18 nickles 19 pennies
Step-by-step explanation:
value of 1 penny=$0.01
value of 1 nickle=$0.05
0.01p+0.05n=1.09
p+n=37
there are two methods for this system
I.substitution
p+n=37
p=37-n
we replace p in the first relation
0.01(37-n)+0.05n=1.09
0.37-0.01n+0.05n=1.09
0.04n=0.72
n=18 nickels
p+18=37
p=37-18=19 pennies
II.reduction
0.01p+0.05n=1.09
p+n=37
we multiply the second equation by 100
p+5n=109
p+n=37
we calculate the difference between the two relations
p-p+5n-n=109-37
4n=72
n=18
p+18=37
p=19

Pythagorean Theorem Quiz.
1.) Find the unknown side length. Simplify answers that are radicals.

3
2.) Find the unknown side length. Simplify answers that are radicals.
16
12
Answer:
1.) 5 2.) 10.58
Step-by-step explanation:
For each one, you use the equation a^2 + b^2 = c^2 where c is the "hypotenuse"-- the side of the triangle opposite (facing) the right angle which is shown with a small box. The variables a and b do not matter, as long as they are the "legs", the other 2 sides.
So it is 4^2 + 3^2 = c^2 which simplifies to 16+9=25=c^2 and square root both sides and you get c=5
and 12^2 + b^2 = 16^2 which simplifies to 144+ b^2 = 256 and subtract 144 from both sides and you get b^2 = 112 and square root both sides and it is approximately 10.6 :)
In the 2006 season, Tom Brady threw for 3,529
yards. In the 2007 season, he threw for 2,806
yards. What is the percentage decrease
Answer:
59.02%
Step-by-step explanation:
SO SORRY THAT THIS IS LATE anyway what you is minus the biggest number by the smallest number which would be 3,529 - 2,806 = 723
BECAUSE 3,529 is the original number you would do 723 / 3,529 = 0.5902521
then you would times that number by 100
0.5902521 x 100 = 59.02%
hope this helps

Answer:
37) -1/3
38) 8/5
39) 0
40) -2/3
Step-by-step explanation:
solve the problem if correct you get brainliest answer.
Answer:
a= 3
b = -6
c = -1
Step-by-step explanation:
Let's start by expanding, since the original is not in a condensed form.
3(x-1)² - 4
3(x-1)(x-1) - 4
(x-1)(x-1) = x²-2x+1
3(x²-2x+1) - 4
3x²-6x+3-4
3x²-6x-1
a= 3
b = -6
c = -1
Malik has two pencils. He has four blue pencils and 2 red pencils. What is the radio of red pencils and blue pencils?
Answer: 2:4 or 1:2
You could also write it in a fraction 1/2
Answer:
2:4
Step-by-step explanation:
We know that Malik has 4 blue pencils and 2 red pencils. Therefore, the ratio of red pencils to blue pencils is 2:4.
# of red pencils : # of blue pencils
2 red pencils : 4 blue pencils
2:4

Can someone tell me how to do a transversal angle measurement with steps and angles
Answer:
Sorry I am not sure but when I figure it out..... I prolly won't
Step-by-step explanation:
Answer:
When two lines are cut by a transversal, the pairs of angles on one side of the transversal and inside the two lines are called the consecutive interior angles . If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary

Solve the following equation for x.
5x + 15 = - 45
Answer:
-12
Step-by-step explanation:
5(-10)=-60
-60+15=
-45
Answer:
-12
Step-by-step explanation:
Reorder the terms:
15 + 5x = -45
Solving
15 + 5x = -45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5x = -45 + -15
Combine like terms: 15 + -15 = 0
0 + 5x = -45 + -15
5x = -45 + -15
Combine like terms: -45 + -15 = -60
5x = -60
Divide each side by '5'.
x = -12 :)
