Lamy can paint 84 portraits in 6 weeks. at this rate , how many portraits can he paint in 2 weeks
lilavasa [31]

Answer:

28 portraits

Step-by-step explanation:

Let's first figure out how many portraits Lamy can paint in 1 week, which is his <u>unit rate</u>. To calculate this, we just have to divide the number of portraits he paints by the amount of time it takes him to paint them.

In this case, the former quantity is 84 portraits, and the latter quantity is 6 weeks, so his unit rate is \frac{84 \text \: portraits}{6 \text \: weeks} = 14 paintings per week.

Now, we know that in 1 week, Lamy can paint 14 portraits. Therefore, since this is a <u>directly proportional relationship</u>, all we have to do to find how many portraits he can paint is 2 weeks is double the unit rate. This is because in a directly proportional relationship, if you multiply one variable by a number, you have to multiply the other by the same number to maintain equality, and here we are multiplying weeks by 2 so we need to multiply paintings by 2 as well.

Thus, Lamy can paint 14 · 2 = 28 paintings in 2 weeks.

Hope this helps!

Answer:

B. -x + 8

Step-by-step explanation:

Given expression

\dfrac{8-4(x-6)}{4}

Consider the numerator 8-4(x-6).

First, use distributive property:

8-4(x-6)=8-(4x-24)

Open the brackets:

8-(4x-24)=8-4x+24

Combine the like terms:

8-4x+24=(8+24)-4x=32-4x

Again use distributive property:

32-4x=4\cdot 8-4x=4(8-x)

Now, the expression is

\dfrac{4(8-x)}{4}=8-x\ \text{or}\ -x+8

Mr. Edwards has a total of 28 kids in his class. There are 6 more boys than there are girls. Write a system
ratelena [41]

Answer:

17 boys and 11 girls

Step-by-step explanation:

Create a system of equations where b is the number of boys and g is the number of girls:

b + g = 28

b = g + 6

Solve by substitution, by substituting the second equation into the first one:

b + g = 28

(g + 6) + g = 28

2g + 6 = 28

2g = 22

g = 11

So, there are 11 girls.

Since there are 6 more boys than girls, there are 17 boys.

So, there are 17 boys and 11 girls in the class.
