Answer: 1 3/5
Step-by-step explanation:
if you have 8 cookies and want to share it with 5 total people you divide it so 8/5 is 1.6
Answer:
7(x-2)=5(x+4)
7x-14=5x+20
7x-5x=20+14
2x=34
x=17
7(x - 2) = 5(x + 4)
Multiply the first bracket by 7
(7)(x)=7x
(7)(-2)=-14
Multiply the second bracket by 5
(5)(x)=5x
(5)(4)=20
7x-14=5x+20
Move 5x to the other side. Sign changes from -5x to +5x.
7x-5x-14=5x-5x+20
7x-5x-14=20
2x-14=20
2x-14+14=20+14
2x=34
Divide both sides by 2
2x/2=34/2
Answer: x=17
The correct answers are:
2, 4, 5, 8, 10, 12, 14, 16, 18, 20
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
6, 12, 18, 24, 30, 36, 42, 48, 54, 60
11, 22, 33, 44, 55, 66, 77, 88, 99, 110
20, 40, 60, 80, 100, 120, 140, 160, 180, 200
60, 120, 180, 240, 300, 360, 420, 480, 540, 600
Explanation:
When finding the first non-zero multiples of a number, we count up by that number. For the twos, we keep adding 2 until we get the first ten terms. We follow a similar process for 5, adding 5 each time until we get the first ten terms.
You can substitute “x” For your answer and solve the problem that way ^^
It’s a a way to “check” yourself.
If it doesn’t fit in and you not get the answer shown the x substitute is incorrect.
I personally think they are right! I also have a test on two step/one step equations lol
Answer: 1 = 69°, 2 = 69°, 3 = 111°
Step-by-step explanation:
The image is that of an isosceles trapezoid. Which means:
∠3 = 111° → refer to #2 above.
Let ∠1 =x, then ∠2 = x → refer to #1 above
2(111) + 2(x) = 360 → refer to #3 above
222 + 2x = 360
2x = 138
x = 69
The two numbers in question obtained by creating a system of equations are 56 and 36
Let the two numbers be : a and b
From (2):
Substitute (3) into (1)
a + b = 92
20 + b + b = 92
20 + 2b = 92
2b = 92 - 20
2b = 72
b = 72/2
b = 36
From (3) :
a = 20 + 36
a = 56
Therefore, the two numbers are 56 and 36
