A is equivalent to angle E
B is equivalent to angle F
C is equivalent to angle G
D is equivalent to angle H
Step-by-step explanation:
1st step is just figuring out which sides corresponds with which.
A is equivalent to angle E
B is equivalent to angle F
C is equivalent to angle G
D is equivalent to angle H
On the last one I am confused by what it is asking, but here is what I think:
The scale factor from the big figure to the small figure is 1.5 because of 15/10=1.5
12/8=1.5 and so on.
5x+3y=58
5x-3y=22
(3y gets cancelled bc 3y-3y=0, then add 5x with 5x, so you're left with)
10x=80, (divide both sides by 10)
x=8
Now we look for y. So choose one formula from the two (let's say 5x + 3y=58)
Substitute x for 8 so it will look like---- 5(8)+3y=58
Multiply 5*8--- so you get -- 40+3y=58
Subtract 40 from both sides and you're left with 3y=18
divide both sides by 3
you get y=6
In conclusion, x=8 and y=6 hence, (8,6)
Answer:
The answer is 358.01
Step-by-step explanation:
Given:
Now, to solve first we crack the power notation then multiply and then do the addition:
(The value of 
is 10 and the value of 
is 1.)
.
Therefore, the answer is 358.01 .
The answer is 10.73 years.
Here, the formula we can use is :
(for the average)
Substitute the values mentioned in the question.
10.54 = (10.35 + Girls)/2
21.08 = 10.35 + Girls
Girls = 10.73 years
Answer:
x = - 9
Step-by-step explanation:
Step 1:
2x - 3 = - 21 Equation
Step 2:
2x = - 18 Add 3 on both sides
Step 3:
- 18 ÷ 2 Divide
Answer:
x = - 9
Hope This Helps :)
