Step-by-step explanation:
14÷2=7
18÷2=9
for the first equation
14/y=7
cross multiply will be
7y=14
divide both sides by the co efficient of y which is 7
y=14÷2
y=2
same step for the second equation
Answer:
35x^2y+49xy^2
Step-by-step explanation:
Multiply 7xy(5x + 7y)
7xy⋅5x+7xy⋅7y
Answer 35x^2y+49xy^2
Answer:
Step-by-step explanation:
Given that :
Summit of Mount Washington = 6288 ft
Location of Carter notch = elevation of 3288 ft
The change in elevation will be :
A reduction in elevation from the summit of Mount Washington to Carter Notch
(6288ft - 3288ft) = 3000ft
Since it is a reduction from the initial elevation point or height, Then the change in elevation will be negative ;
= - 3000ft
