Answer:a) L.C.M OF 2,3,5 is 30
THEREFORE=60/30+15/30÷10/30-6/30
=60/30+15/30×30/10-6/30(DMAS)
=60/30+3/2-6/30
=60+45/30 -6/30(ADDITION FIRST THEN SUBTRACTION.
=105/30-6/30
=105-6/30
=99/30
=33/10
b)(3+1/2)÷(2-1/2)=L.C.M IS 2,=(6+1/2)÷(4-1/2)=7/2÷3/2=7/3
We can use the points (2, 8) and (4, 12) to solve.
Slope formula: y2-y1/x2-x1
= 12-8/4-2
= 4/2
= 2
Based on the question, we need to put the equation in slope-intercept form (y = mx + b).
Let's solve for the y-intercept. (We can use the point 2, 8 to solve).
y = 2x + b
8 = 2(2) + b
8 = 4 + b
8 - 4 = 4 + b - 4
4 = b
Now, that we know what the slope and y-intercept is we can put this into the final equation.
y = 2x + 4 (third option)
Best of Luck!
Answer:
C
Step-by-step explanation:
X-Axis goes by 4, so 77° falls around the 30-40 area.
You must get the like terms on the correct sides, so here is how to solve it:
First subtract 5x from both sides: 3x+4=-11
Then subtract 4 from both sides: 3x=-15
Finally divide by 3: x=-5
Brand A 1.12/12 = .093 rounds to .09 cents each.
Brand B 2.69/25 = .1076 rounds to .11 cents each
Brand A is the better buy because it is cheaper
