Answer:
379/100
Step-by-step explanation:
IS THIS IT???
If you're confused whether to do multiplication or division first.
<span>Remember PEMDAS. It's the Order of Operation. Basically, it's the order of which operators are prioritized in an equation.
From Highest to Lowest Priority.
Parentheses, Exponents, (Multiplication and Division), and (Addition and Subtraction)
Multiplication and Division have the same priority, as well as Addition and Subtraction.
So for this it is which ever comes first, from left to right of the equation is prioritized.
WORKING:
3x2/3
The multiplication operator comes first, so we do:
3 x 2=6
Finally, we take "6" and divide it by 3
6 / 3 = 2
Answer is: 2</span>
Answer:
Step-by-step explanation:
Midpoint: M=(14,26)=(xm,ym)→xm=14, ym=26
One endpoint: A=(32,40)=(xa,ya)→xa=32, ya=40)
Other endpoint: B=(xb,yb)→xb=?; yb=?
xm=(xa+xb)/2
Replacing xm=14, and xa=32
14=(32+xb)/2
Solving for xb. Multiplying both sides of the equation by 2:
2(14)=2(32+xb)/2
28=32+xb
28-32=32+xb-32
-4=xb
xb=-4
ym=(ya+yb)/2
Replacing ym=26, and ya=40
26=(40+yb)/2
Solving for yb. Multiplying boths sides of the equation by 2:
2(26)=2(40+yb)/2
52=40+yb
52-40=40+yb-40
12=yb
yb=12
B=(xb,yb)→B=(-4, 12)
Answer: the coordinates of B are (4,12)
Answer:
Andy ate 41 hot dogs
Barry ate 36 hot dogs
Carl ate 26 hot dogs
Step-by-step explanation:
Let the quantity of hot dogs eaten by Andy, Barry and Carl be A, B and C respectively.
Andy ate 5 more than Barry =>
A = B + 5. (Equation i)
Carl ate 10 less than Barry =>
C = B - 10. (Equation ii)
The three atr the total or 103 hot dogs.
ie. A + B + C = 103 (Equation iii)
From i and ii, substitute (B + 5) for A and (B - 10) for C in equation (iii)
(B + 5) + B + (B - 10) = 103
B + 5 + B + B - 10 = 103
B + B + B + 5 - 10 = 103
3B - 5 = 103
3B = 103 + 5
3B = 108
B = 108/3
B= 36
From equation (i)
A = B + 5
A = 36 + 5
A = 41
From equation (ii)
C = B - 10
C = 36 - 10
C = 26
Andy ate 41 hot dogs
Barry ate 36 hot dogs
Carl ate 26 hot dogs
