You and your friend Sam are going to paint your 300 square feet room together.

1 answer:

4 0

Fraction that Sam painted in 1 min is:
10/25=2/5
Fraction that you painted in 1 min:
5/25=1/5

Fraction pained by both in 1 min:
1/5+2/5=3/5 ft²/min
Time taken to paint 50 ft² will be:
time=3/5×50=30 min
Thus we conclude that Sam was wrong.

M has to equal 2. 11-5 equals 6. 6-4 is 2. 2 is the missing value.

Is line m: -x+2y=6 parallel, perpendicular, or neither parallel nor perpendicular to line n: y=-2x+6?

Serhud [2]

Make them both equal to y

y=-2x+6

2y=x+6 y=1/2x+3

These are perpendicular since ones slope is -2 and the other is the opposite, 1/2.

At the movie theatre, child admission is $5.20 and adult admission is $8.60. On Sunday, 132 tickets were sold for a total sales

xxMikexx [17]

Answer:

60 tickets for children were sold

Step-by-step explanation:

Let x be the number of sold children's tickets and let y be the number of adult tickets sold, then we can pose the following equations.

$x + y = 132$ (i) Because 132 tickets were sold in total

$5.20x + 8.60y = 931.20$ (ii) because the total of $ obtained by sales was 931.20.

We must clear x. Then we substitute (i) in (ii)

$5.20x +8.60(132-x) = 931.20$

$5.20x + 1135.2 - 8.60x = 931.20$

$-3.4x = -204$

$x = 60$
