Answer:
39x - 63
Step-by-step explanation:
5(3x - 3) + 4(6x - 12) ← distribute both parenthesis
= 15x - 15 + 24x - 48 ← collect like terms
= 39x - 63
Answer:
Step-by-step explanation:
y = 3.2x+5
This equation represents a straight line where 3.2 is the slope of the line and 5 is the intercept of the line on the y-axis (basically where the line touches the y-axis)
So,because this is a line you only need two points to draw it.
One point you already know it's y =5.
To find another point that lies on the line just substitute a convenient number for x.For example say if x= 1/3.2
y = 3.2*( 1/3.2) +5
Therefore:
y = 1+5 =6
So,the other point on the line is (1/3.2 , 6)
Now find the points y = 5 and (1/3.2 , 6) on the xy plane and draw the line passing through them.
1). 140 tomatoes
7/5= 1.4
1.4(100)=140
2). 41 people
58/1.4= 41.4
That would not be possible in fraction form, since 7 does not have any whole number factors, and decimals are not allowed in fractions.
