Answer:
1/5x - 12 = -7
Step-by-step explanation:
The first thing says 12 less THAN. Normally, when you see something in word problems like "less than" it means you need to switch the places.
So rather than 12 - 1/5, it's 1/5 - 12.
1/5 of a number means you are multiplying that number by 1/5. we'll use x (or any letter really, doesn't matter) to represent the unknown number.
Remember that if a variable and number is written together, it means multiplication.
So, 1/5x - 12 = -7.
You can make 14 quarter pounders
1=4
2=8
3=12
1/2=2
12+2=14
Hope it helps!
Answer:
(c) 40
Step-by-step explanation:
Let the resultant of the two vector is R
So
Squaring both side
We know that
So
Taking right part
Now taking left part
So the value of resultant should be in between 30 and 70
Which is 40 in the option so option c is correct option
I assume the 38º measurement refers to the measure of arc BE. Then
and so
(I think the theorem I used here is called "angle of intersecting secants")
Answer:

Im not sure but let me know if it's wrong
round it to 34%
