Actually Welcome to the Concept of the Ration and Percentage,
To get the Adams rake,
let's calculate 5% of 357 ltrs.
therefore, (5/100)* 357 = 17.85 ltrs
let's subtract the 5 % value from Tapiwa rake,
==> 357 - 17.85 == 339.15
hence the Adams rake is 339.15 ==> round off ==> 339 litres.
Answer:
(x+4)(x-7)
Step-by-step explanation:
Answer:
7x + 2
Step-by-step explanation:
Original Equation: 3x − ( −2 − 4x)
First, we distribute the negative sign:
= 3x + (−1) (−2−4x)
=3x + (−1)(−2) + (−1)(−4x)
= 3x + 2 + 4x
Using the communitive property of addition, we can write:
= 3x + 4x + 2 (Instead of 3x + 2 + 4x)
Combining like terms, we get:
= (3x + 4x) + 2
= 7x + 2
40 x 3 = 120 students study languages
there are 40 students in each language class and there are 3 language classes.
hope it's clear :)
