4 ) Here is an explanation that the angle sum of triangle ABC is 180º.
The reasons for each line are missing.
Give the reasons.
1. Angle A of the triangle = angle PCA
2. Angle B of the triangle = angle QCB
3. Angle PCA + angle C of the triangle + angle QCB = 180°
Hence angle A + angle B+ angle C = 180°

3x+2y=15
y=6x
Answers
3x + 2(6x) = 15
3x + 12x = 15
15x = 15
X = 1
Answer:
x = 1
Step-by-step explanation:
3x +2y = 15
y = 6x
Substitute y for 6x in 3x +2y = 15!
3x + 2(6x) = 15
3x + 12x = 15
Combine like terms

How many months does it take to earn $180 in interest on an investment of the principal is $5000 and the interest rate is 2%?
Answers
Answer:
months = 6.67
Step-by-step explanation:
time in years = interest / (principal amount x rate)
time in y = 180 / (5000 x 0.02)
time in y = 180 / 100
time in months = 12 / 1.8
months = 6.67

Answer:
5) ?
6) y = 55
7) no variable equals 101 in this triangle
Step-by-step explanation:
5) There was no question for 5
6) This is the answer because:
x = 79: 65+36+x = 180, 101+x = 180, x = 79
z = 144: 180 - 36 = 44
y = 55: 36+79+(y+10) = 180, 115+(y+10) = 180, y+10 = 65, y = 55

Gaurav takes 15 rounds of a rectangular park whose length is twice its breadth. If the total distance covered by Gaurav is 900m find the length and breadth of the park
Answers
Answer:
length = 20 breadth = 10
Step-by-step explanation:
divide 900 by 15
= 60
60 divided by 6 because the length is twice the breath
60 / 6 is 10
so ten is the breadth of one side and double that is 20 so the length is 20

Eight toy camels and three toy pigs cost Gary $85. Twelve toy camels cost Sherry $96. Assuming everyone bought their toys at the same store and there were no discounts, what is the cost of two toy pigs?
Answers
Answer:
2 toy pigs cost $14
Step-by-step explanation:
If 12 toy camels cost $96, I can solve ($96 / 12 = $8) to find the price of 1 toy camel. Now, I know that 1 toy camel costs $8.
If 8 toy camels and 3 toy pigs cost $85, I can multiply the price of 1 toy camel by 8 and solve ($8 x 8 = $64).
Next, I can subtract Gary's total cost by the toy camels to find how much was spent on 3 toy pigs. ($85 - $64 = $21) Therefore, 3 toy pigs cost $21.
Then, I can solve ($21 / 3 = $7) to find the price of 1 toy pig. Finally, I can multiply ($7 x 2 = $14) to find that 2 toy pigs cost $14.
Answer:
Two toy pigs cost $14.
Step-by-step explanation:
Gary bought 8 toy camels and 3 toy pigs for $85.
Sherry bought 12 toy camels for $96.
Thus, each toy camel cost $96/12=$8
Now we know Gary spent 8*$8= $64 in toy camels.
The rest of the $85, $85 - $64 = $21 was spent on the 3 toy pigs, thus each toy pig cost $21/3=$7
If one toy pig costs $7, two toy pigs cost $14.
Helppoo 10 points! I’ll mark brainliest!
Answers
Answer Yes, because you take the answer from 100+45 and subtract 3 to get to 97 and then you add 29 to make the 47 a 74.
Step-by-step explanation:
100+45 = 145
pattern: add 2 to 98 and subtract 2 from 47 to get the second equation (100+45)
you cannot use the pattern 97+47 because if you follow the pattern of the first equations you will not get the correct answer! You would get (99+45=144)
Vincent purchased a scooter for $124 before tax. The store adds a 7.8% sales tax to every purchase. How much did Vincent pay for the scooter, to the nearest penny?
Answers
Step-by-step explanation:
Original price of the scooter = $124
Sales Tax = 7.8%
Price of the scooter after tax = 124 + 7.8%(124)
= 124 + 7.8/100 x 124
= 124 + 3.9/50 x 124
= 124 + 1.95/25 x 124
= 124 + 0.39/5 x 124
= 124 + 0.39 x 24.8
= 124 + 9.672
= 133.672
Therefore, after tax the scooter will cost $133.672.
Find the length of side x in simplest radical form with a rational denominator
Answers
Answer:
The length of x=3/1
Step-by-step explanation:
Given the right triangle
Ф = 30
We know that
sin Ф = opposite/hypotenuse
The opposite of angle 30° = x
The hypotenuse is = 6
so
sin 30 = opposite/hypotenuse
1/2 = x/6 ∵ sin 30 = 1/2
1/2 × 6 = x
6/2 = x
3/1 = x
Therefore, the length of x=3/1
