Step-by-step explanation:
step 1. 2x + 3x + 4x = 180° internal triangle angles add up to 180°
step 2. 9x = 180 or x = 20
step 3. <A = 2x = 2(20) = 40°
step 4. <B = 3x = 3(20) = 60°
step 5. <C = 4x = 4(20) = 80°.
Answer:
I think its A correct me if wrong

help me with this please
Answer:
Step-by-step explanation:
if 45+47=t and t=45+47 t would equal 92 in both
45+47<t than t<45+47
so basically its saying 92<t (92is less than t) and t<92 (t is greater than 92)
he is not right. When you have an equation like that the answer is 92. Its not going to be greater or less than 92. It is 92. It should be t=92
hope that masks some kind of sense. It after 1am here so I apologize if it doesn't sound right...

Working alone it takes mark 7 hours to mop the whole house it takes sue 9 determine to the nearest hundredth of the hour how long it will take then to mop the house together
Answer:
3.9375 hours
Step-by-step explanation:
Working alone it takes mark 7 hours to mop the whole house it takes sue 9 determine to the nearest hundredth of the hour how long it will take then to mop the house together
This is calculated as
1/Time it would take them to work together = 1/ Number of hours Mark mopped + 1/ Number of hours Sue mopped
= 1/T = 1/7 + 1/9
Lowest common denominator = 63
1/T = 9 + 7/63
1/T = 16/63
T = 63/16
T = 3.9375 hours

A ball is rolled uphill a distance of 4 meters before it slows, stops, and begins to roll back. The ball rolls downhill 12 meters before coming to rest against a tree. What is the ball's displacement?
Answer:
8
Step-by-step explanation:
A ball is rolled uphill a distance of 4 meters
The ball rolls downhill 12 meters before coming to rest
Therefore the ball displacement can be calculated as follows
= 12-4
= 8
Hence the displacement is 8

solve for x
similar triangles advanced
Answer:
x = 2.57
Step-by-step explanation:
6/x = 7/3
7x = 18
x = 2.57
check:
if x = 2.57
then:
2.57/6 = 3/7
0.4283 = 0.4283
that checks as correct

The sum of two numbers is 41 and the difference is 17 what are the numbers?
Answer:
29 and 12
Step-by-step explanation:
x + y = 41
x - y = 17
Adding the two equations:
x + y + x - y = 41+17
2x = 58
x = 58/2
x = 29
Substituting 'x' into the first equation:
29 + y = 41
y = 41-29
y = 12

Frank made cookies for his class. He gave away half of them in his first period class, but then his mom dropped off 12 more cookies. If he now has 32 cookies, how many did he start with?
Answer:
Work backwards to solve this problem.
If he ends with 32 cookies, then subtract 12. That gives 20 cookies. 20*2 is 40, so now he has 40 cookies.

What value of x satisfies the equation below?
[tex]\frac{-2x - 6}{5} = 4[/tex]
Answer: -13
Step-by-step explanation:
1. Isolate x: move 5 to the otherside
=> -2x-6=4*5 => -2x-6=20
2. Move 6 to the otherside: -2x=20+6 => -2x=26
3. Divide both sides by -2
=> x=26/-2 => x=-13

Count to find the slope. Write your answer clearly.
Answer:
[tex]-\frac{1}{4}[/tex]
Step-by-step explanation:
To find the slope by graph, we can use [tex]\frac{rise}{run}[/tex]
The point (5, -3) rise 1 and run 4 to get to (1, -2).
However, the function run from the upper quadrant to the bottom quadrant making it negative.
