The answer is 50 & 24
x - the bigger number
y - the smaller number
<span>The sum of a number and two times a smaller number is 98:
x + 2y = 98
</span><span>The bigger number is 22 less than three times the smaller number:
x = 3y - 22
</span>x + 2y = 98
x = 3y - 22
________
3y - 22 + 2y = 98
5y - 22 = 98
5y = 98 + 22
5y = 120
y = 120/5
y = 24
x = 3y - 22
x = 3 * 24 - 22
x = 72 - 22
x = 50
Answer: 22.5 yards
Step-by-step explanation:
There are a total of 20 parts yarn. This means that 3/20 of the carpet is silver. So in order to compare this to the 150 meters of total yarn, you would set up this equation:
3/20 = x/150
Next, you cross multiply:
3*150 = 20*x or simplified would be 450 = 20x
Next, you divide both sides by 20 to get x by itself.
450/20 = 22.5, so x is equal to 22.5
This means you have 22.5 yards of silver in the carpet.
150. answer is 150. divide 375 by 2.5.
Answer:
I think x=-25
Step-by-step explanation:
Answer:
Step-by-step explanation:
Adding the two equations together gives you
9x-10y-9x-6y=145+15
-16y=160
y=-10, using this value in 9x-10y=145 gives you
9x-10(-10)=145
9x+100=145
9x=45
x=5
So y=-10 and x=5
