Answer: 8
Step-by-step explanation: Because a is perpendicular to b, the value of 9x + 18 = 90. If we subtract 18 from both sides, it becomes 9x = 72. Divide by 9 on both sides to get 8
Do 34x 3 and multiply that also by 3 Hope that helped :)
It would be C, because the ratio 2/5 (the ratio of giraffes to monkeys) is equal to 4/10 (answer choice C)
Answer:x=8,y=1
Step-by-step explanation:
2x+4y=20
So, 4y=20-2x
So,2y=10-x
Now we can use this information to use in the second equation
3x+2y=26
3x+(10-x)=26
2x+10=26
2x=16
x=8
Now that we know that x=8, then we can solve for y.
2x+4y=20
2(8) +4y=20
16+4y=20
4y=4
y=1
Answer:
a.-3
b. y=-3x-1
c. y=-3x-1
d. 3x+y=-1
