Answer:
450 grams
Step-by-step explanation:
Let's create a proportion using the following setup:
sugar/people = sugar/people
We know that 150 g of sugar can serve 6 people.
150 g/ 6 people = sugar/people
We don't know how much sugar can serve 18 people. So, we can say x can serve 18 people.
150 g/ 6 people = x g/ 18people
150/6=x/18
We want to find x, so we need to get x by itself. x is being divided by 18. The inverse of division is multiplication. Multiply both sides of the equation by 18.
18*(150/6)=(x/18)*18
18*150/6=x
18*25=x
450=x
x= 450 g
450 g of sugar is needed to make bread for 18 people.
Answer:
y=3x-9
Step-by-step explanation:
Hi there!
we are given a point (4,3), and a line (y=-1/3x+4)
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
first, let's find the slope of the new line.
we can find it with this formula: (m=slope)
-1/3m=-1
multiply both sides by -3
m=3
here's our equation so far, written in y=mx+b form, where m is the slope and b is the y intercept
y=3x+b
we need to find b
Because the line passes through the point (4,3), we can use it to find b
substitute x as 4 and y as 3
3=3(4)+b
multiply
3=12+b
-9=b
substitute into the equation
<u>y=3x-9</u>
Hope this helps!
