1: A triangle's angles add up to 180
180 - 130 = 50
50 / 2 = 25
x = 25
2: The sides given will be equal as this is a right-triangle
24 = 3(x + 2)
24 = 3x + 6
18 = 3x
x = 6
3: There is a lot of writing so I am unable to see the original triangle
(sorry *nervous sweat*)
4: A triangle's angles add up to 180, and the two sides given will be equal
5y = 20
y = 4
The angles in the bottom-most triangle are all equal to 60 as 180 / 3 = 60.
90 - 60 = 30.
x = 30

If car number plates have 3 English alphabet letters followed by 3 digits, how many of these start with ABC?
Answers
Answer:
351520000
Step-by-step explanation:
351520000
Explanation:
There are 10 possible digits for the numbers (0,1,2,...,9), and 26 possible letters (A,B,C,.....,Z).
Since repetitions are allowed, we have that for each letter used, 26 still remain for the next choice, and for each digit used, 10 still remain for the next choice.
Hence, by the multiplication principle, the total different number of letter permutations is
26

and the total number of digit permutations is

But now since they can be in any order, we basically require in how many different ways can 3 be chosen from 6 which is the combination

So for each of the original permutations of numbers and letters, we must consider the 20 different combinations of positions they can be in.

How do you solve the equation 4a+b=12
Answers
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*a+b-(12)=0
Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 4a+b-12 = 0 and calculate its properties
Notice that when a = 0 the value of b is 12/1 so this line "cuts" the b axis at b=12.00000
b-intercept = 12/1 = 12.00000
When b = 0 the value of a is 3/1 Our line therefore "cuts" the a axis at a= 3.00000
a-intercept = 12/4 = 3
Slope is defined as the change in b divided by the change in a. We note that for a=0, the value of b is 12.000 and for a=2.000, the value of b is 4.000. So, for a change of 2.000 in a (The change in a is sometimes referred to as "RUN") we get a change of 4.000 - 12.000 = -8.000 in b. (The change in b is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -8.000/2.000 = -4.000
Geometric figure: Straight Line
Slope = -8.000/2.000 = -4.000 a-intercept = 12/4 = 3 b-intercept = 12/1 = 12.00000Answer:
Step-by-step explanation:
Without having a numerical value for a (or b), you can't "solve this equation."
You can, however, solve it for either a or b, but not both.
For a: Subtract b from both sides. This results in 4a = 12 - b. Dividing both sides by 4 isolates a:
12 - b
a = --------------
4
For b: Subtract 4a from both sides. Then: b = 12 - 4a

How do I solve this?
Answers
Answer:
100 miles.
Step-by-step explanation:
The combined speed of the 2 trains = 38 + 42 = 80 mph.
The time taken before they crossed = 15:35 - 14:20
= 1:15 = 1.25 hours
Speed = distance / time, so
80 = distance / 1.25
Distance = 80 * 1.25
100 miles.
Answer:
100 miles
Step-by-step explanation:
A -----------P------------------ B
tom start at 14:20 with speed of 38mph
ben with speed 42mph
meeting time is 15:35
time difference is 75 min = 75/60 = 1.25 hours
distance travelled by tom is AP
AP = v * t
= 38 * 1.25
= 47.5 miles
distance travelled by ben is BP
BP = v * t
= 42 * 1.25
= 52.5 miles
distance between two cities is AB = AP + PB
= 47.5 + 52.5
= 100 miles

Sean bought 1.8 pounds of gummy bears and 0.6 pounds of jelly beans and paid $10.26. He went back to the store the following week and bought 1.2 pounds of gummy bears and 1.5 pounds of jelly beans and paid $15.09. What is the price per pound of each type of candy?
Answers
Answer:
Gummy bears $3.20/lbs
Jelly beans $7.50/lbs
Step-by-step explanation:
For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):
1.8x + 0.6y = 10.26
1.2x + 1.5y = 15.09
Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)
