Solution: X=9.5
Explanation: x-5.5=4 —> x=4+5.5 —> x=9.5
x*5 - quarter amount
(x+15)*25- nickels amount
(x*5)+((x+15)*25)=735
5x+25x+375=735
30x=735-375
30x=360
x=360/30=12 - number of nickels
x+15=12+15=27 - number of quarters
CHECK
12*5=60 ¢
27*25=675 ¢
675+60=735 ¢ or $7.35
Given : Shopkeeper had 10m Cartons of Eggs
Given : He sold 2 of the Cartons and used 1 Carton to cook for his Family
⇒ Shopkeeper took 3 Cartons of Eggs form 10m Cartons of Eggs
⇒ The Shopkeeper is left with (10m - 3) Cartons of Eggs
Option (1) is the Answer
Step-by-step explanation:
slope = x factor = - 5/2
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
New slope = 2/5 = m
y = mx + b
from the point given y = 2 | x = -4
2 = (2/5 × -4 ) + b
2 = - 1.6 + b
b = 3.6
line equation
Answer:
0.05 + 0.1y = 0.12 + 0.06y
Step-by-step explanation:
Here, we want to find y which is the heat in which the amount of mercury in each of the water bodies is same.
Now for the first water body:
Initial is 0.05 ppb and after y years, we have a rise of 0.1 * y = 0.1y ppb
So the amount of mercury in ppb after y years would be; 0.05 + 0.1y
For the second water body;
Initial is 0.12 and a rise of 0.06 ppb per year for y years. The rise would be 0.06 * y = 0.06y
So total amount of mercury here is 0.12 + 0.06y
So to find y which is the year the amount of mercury in each water body is same, we simple equate both and that would be;
0.05 + 0.1y = 0.12 + 0.06y
