4 (3x+9)-3(5y+7) =11
distribute
12x +36 -15y -21 =11
12x -15y +15 =11
subtract 15 from each side
12x -15y =-4
subtract 12x from each side
-15y= - 12x-4
divide by -15
y = -12/-15 x -4/-15
y = 4/5 x + 4/15
slope = 4/5
y intercept = 4/15
<span>A. Consumer price index measures the change in prices of specific good and services over time. The consumer price index (CPI) is an estimate of prices that are collected periodically that represent the item/goods. CPI is based on the overall cost of a fixed basket of goods a typical costumer would buy rather then the same basket in the year.</span>
I think it's 34.5 (I need more letters so I'm typing this)
Subtract 3 both sides first. R-3=ts²
next, divide both sides by t, (R-3)/t=s²
finally, take the square root of both sides
√(R-3)/t = s. 2nd choice.
Answer:
1 meter.
Step-by-step explanation:
1 1/2 * 1/3
= 3/2 * 1/3
= 3/6
= 1/2.
So John used 2*1/2 = 1 meter of the ribbon.
