Step-by-step explanation:
2×2.5x+2×8=11
5x+16=11
5x=11-16
5x=-5
x=-1
Answer:
x = -1
Step-by-step explanation:
2(2.5x + 8) = 11
Divide both sides by
2.5x + 8 = 5.5
Subtract 8 from both sides
2.5x = -2.5
Divide both sides by 2.5
x = -1

Answer:
40 minutes.
Step-by-step explanation:
First, you divide 30 minutes by 6 miles, so you can see how long it takes to complete 1 mile. It takes 5 minutes. Now, multiply 8 by 5 and you get 40 minutes.
Answer:
30 mins ---- 6 miles
? mins ---- 8 miles
30 mins - 6 miles
40 mins - 7 miles
50 mins - 8 miles

Answer:
75
Step-by-step explanation:
Volume = 1/2*B*H
So 10 times 3 times 5 divided by 1/2. 10 times 3 is 30, multiplied by 5 is 150.
150 divided by 0.5 (1/2) is 75.
For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?
Remember money is rounded to the nearest hundredth.
Answer:
2 dollars
Step-by-step explanation:
Answer:
$1.72
Step-by-step explanation:
First, subtract the cupcake from the total
44.03-2.75=41.28
Find out the total number of cookies
8+16=24
Then divide the total cookie price by the total number of cookies
41.28÷24=1.72
Each cookie costs $1.72

Answer:
x = 5
Step-by-step explanation:
6*(2x+8) = 108
12x + 48 = 108
x =60/12
x = 5
Answer:
x = 5 units
Step-by-step explanation:
The area of a rectangle equals length times widths, therefore we can use the information from the question to make the following equation...
108 = (2x + 8)(6)
Now we just solve the equation and get...
108 = (2x + 8)(6)
108 = 12x + 48
12x = 108 - 48
12x = 60
x = 60 / 12
x = 5
Therefore, x = 5 units.
Tyler’s class played the block game using purple, orange, and yellow bags of blocks.
- During round 1, Tyler’s group picked 4 purple blocks and 12 blocks of other colors.
- During round 2, Tyler’s group picked 11 orange blocks and 5 blocks of other colors.
- During round 3, Tyler forgot to record how many yellow blocks his group picked.
For a final round, Tyler’s group can pick one block from any of the three bags. Tyler’s group decides that picking from the orange bag would give them the best chance of winning, and that picking from the purple bag would give them the worst chance of winning. What results from the yellow bag could have lead Tyler’s group to this conclusion? Explain your reasoning.
Answer:
A
Step-by-step explanation:
- During round 1, Tyler’s group picked 4 purple blocks and 12 blocks of other colors.

A man is trying to zombie-proof his house. He wants to cut a length of wood that will brace a door against a wall. The wall is 4 feet away from the door, and he wants the brace to rest 2 feet up the door. About how long should he cut the brace?
Answer:
Assuming you're rounding to the nearest tenth, he should cut the brace 4.5 feet long.
Step-by-step explanation:
Since this is a right triangle, you can use the a^2 + b^2 = c^2 easily.
You can use either 2 or 4 as the a or the b.
After filling in the equation, 2^2 + 4^2 = c^2, you can calculate it to find it is 4 + 16 = c^2.
If you add 16 + 4, you get 20. So now, you need to find the square root of 20 which is 4.4721 but if you round to the nearest tenth, you get 4.5^2.
He should cut the brace to 4.5 square feet.

can the counting principle be used to help you figure out the number of favorable outcomes? Why or why not
Answer:
Um i dont think so
Step-by-step explanation:
Answer:You can use the Counting Principle to find probabilities of events. The probability of any event is equal to the ratio of favorable outcomes to the total number of equally likely possible outcomes. Favorable outcomes are the outcomes you are looking for.

Can yall please help me with this, i have a concussion I think but I dont wanna tell my family! So please this was due last week!
Answer:
I only know the answer to number 13, and it is 61°
Step-by-step explanation:
Since I go to RSM, I learned something called a remote interior angle theorem. Basically, the exterior angle is equal to the two angles that are on the far side of the triangle. So if you do 145-74, you get 61°.
Answer: 61°

Please answer question below
Which dimensions can create only one unique triangle?
A.) 3 angles measuring 75 degrees, 45 degrees, and 50 degrees
B.) 3 sides measuring 14 m, 11 m, and 18 m
C.) 3 angles measuring 40 degrees, 50 degrees, and 60 degrees
D.) 3 sides measuring 3 cm, 4 cm, and 8 cm
Answer:
B)
Step-by-step explanation:
A, C, and D multiple choice answers have no chance of becoming a triangle because the lengths don't add up to either 180 or 90. Also, Triangle B follows the rule that 2 sides and be greater than the other side.
Answer: Choice B)
3 sides measuring 14 m, 11 m, and 18 m
=================================================
Explanation:
Let's go through choices A through D to see which result in one unique triangle, or could produce (infinitely) many triangles, or produce no triangles at all.
Choice A produces no triangles at all. Why is this? The angles don't add up to 180. We see that 75+45+50 = 170. The three angles must add to 180 degrees for a triangle to form. Choice B produces one single triangle, which is why it's the final answer. The triangle inequality theorem can be used here to show that a triangle can be formed. The SSS (side side side) congruence theorem is then used to show that exactly one unique triangle is possible. Choice C is a similar story to choice A. We can rule it out. This time we have the angles add to 40+50+60 = 150 which is short of 180.Choice D can be ruled out too. The two sides a = 3 and b = 4 add to a+b = 3+4 = 7, but that's smaller than c = 8. We must have a+b > c to be true if we wanted to form a triangle. For more info, see the triangle inequality theorem.Even if the angles did add to 180 (for either choice A or choice C), then we'd have infinitely many triangles and not one unique triangle. Think of dilating the triangles and how each dilated image retains the same angles. In other words, the triangles keep the same shape. Simply knowing the three angles is not enough info to create one unique triangle. We would need to know some info about the sides. This explains why AA or AAA is not a congruence theorem.
