Answer:
-3/2
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. That means that it's the reciprocal, but with the opposite sign. The slope of a line perpendicular to a line with slope 2/3 would be -3/2. Here's how to figure it out:
Start with the slope: 2/3
Flip the fraction to find the reciprocal : 3/2
The sign has to be changed! So the negative reciprocal is -3/2.
Answer:
Number of 1 point shots = 16
Number of 2 point shots = 36
Step-by-step explanation:
Let,
x be the number of 1 point shots
y be the number of 2 point shots
According to given statement;
x + y = 52 Eqn 1
x + 2y = 88 Eqn 2
Subtracting Eqn 1 from Eqn 2
x + 2y - x - y = 88 - 52
y = 36
Putting y = 36 in Eqn 1
x + 36 = 52
x = 52 - 36
x = 16
Hence,
Number of 1 point shots = 16
Number of 2 point shots = 36
X = x4
And
Y = x2
Because of the fact the cows have 4 legs and chickens have 2
Answer:
First, our answer is 18 yards long.
Step-by-step explanation:
It is 18 yards long because first, we have 9, the length of Jamie's car. Joey's car length is 27 feet. Then, since 1 foot converted is 0.333333...., it is very hard to convert so i turn it in to 9 foot converted into 3 yards. Then, both sides multiply by 3 so 27 foot equals to 9 yards. 9 yards+9 yards equals 18 yards.
Hope it helps Hailey!

Answer:
65 tickets for children
Step-by-step explanation:
In this case we can solve it by means of a 2x2 system of equations, like this:
Let x be the ticketsr of children
let y be the tickets of adults
Thus:
5.3 * x + 9.4 * y = 852.1
x + y = 119 => x = 119 - y
replacing, we are left with:
5.3 * (119 - y) + 9.4 * y = 852.1
630.7 - 5.3 * y + 9.4 * y = 852.1
9.4 * y - 5.3 * y = 852.1 - 630.7
4.1 * y = 221.4
y = 221.4 / 4.1
y = 54
Now to calculate x:
x = 119 - 54
x = 65
Which means that there are 65 tickets for children and 54 tickets for adults.
