The ordered pair is (-2, -3)
Step-by-step explanation:
- Step 1: To find whether an ordered pair is a solution, substitute values of x and y and see whether it satisfies the equation.
(-3, -2) ⇒ 7 × -3 - 5 × -2 = -21 + 10 = -11 ≠ 1
(-2, -3) ⇒ 7 × -2 - 5 × -3 = -14 + 15 = 1
(0, 4) ⇒ 0 - 5 × 4 = 20 ≠ 1
(4, 0) ⇒ 7 × 4 - 0 = 28 ≠ 1
So the ordered pair is (-2, -3)
Answer:
66%
Step-by-step explanation: 2/3 is .66666666666666...
Answer:
60%
Step-by-step explanation:
First, find the total number of sixth graders
To do this, add the number of girls and boys together
girls+boys
There are 60 girls and 90 boys
60+90
150
Now, find the percent of sixth graders that are boys
To do this, divide the number of boys by the total number of sixth graders
boys/total sixth graders (part/whole)
There are 90 boys, and 150 total sixth graders
90/150
0.6
Convert to a percent. Multiply by 100 or move the decimal place two spots to the right
0.6*100=60
0.6-->6.0-->60.
So, 60% are boys
30 b/c 60 x 1/2= 30
Answer= 30
Answer: 4y/(y+3)
Explanation:
{(2y)(4y-12)}/{(y-3)(2y+6)}
= (8y^2 - 24y)/(2y^2 + 6y - 6y - 18)
= (8y^2 - 24y)/(2y^2 - 18)
= {8y(y-3)}/{2(y+3)(y-3)}
= 2 * 4y/{2(y+3)}
= 4y/(y+3)
