Answer:
Original number is 86
Step-by-step explanation:
Original: 10x + y
Double reversed: 2(10y + x)
Constraints:
x + y = 14 ===> x = 14 - y
2(10y + x) + 10x + y = 222 ===> 21y + 12x = 222
Substitution to find y:
21y + 12x = 222
21y + 12(14 - y) = 222
21y + 168 - 12y = 222
9y + 168 = 222
9y = 54
y = 6
Substitution to find x:
x = 14 - y
x = 14 - 6
x = 8
Original: 10x + y
10(8) + (6)
80 + 6
86
Answer:
the length of one side is 120
Step-by-step explanation:
let the length = x
we need to form an equation to find the side...
since its 10 per metre
10x = 1200
x = 1200/10
x=120
hope it helped !
Answer:
5
Step-by-step explanation:
sum the parts of the ratio, 3 + 4 = 7 parts
Divide the number of students by 7 to find the value of one part of the ratio
35 ÷ 7 = 5 ← value of 1 part of the ratio, then
3 parts 3 × 5 = 15 ← number of boys
4 parts = 4 × 5 = 20 ← number of girls
20 - 15 = 5
There are 5 more girls than boys

Answer:
1. 4463
2. no
Step-by-step explanation:
1. Put the value of x into the equation and do the arithmetic.
f(4) = 5000(0.972^4) ≈ 5000·0.8926168 ≈ 4463.08
There will be about 4463 lemmings in 4 years.

2. An exponential function has the variable in the exponent. When the variable is the base of a term that has an integer constant exponent, we call it a polynomial function.
The function is NOT an exponential function.
