Answer:
3(9m + 13) - (m + 10) = 1
Step-by-step explanation:
Here, we want to write an equation we can use to find the age of Mario.
Let the present age of Mario be M
Age of Sarah is 3 years older than 9
times Mario’s age
Mario’s age is thus;
9m + 3
In ten years, she will be 1 less than triple his age
In 10 years time, sarah age will be 9m +
3 + 10 = 9m + 13
Mario age will be m + 10
Mathematically;
3(9m + 13) - (m + 10) = 1
Answer:
96
Step-by-step explanation:
Exterior angles add up to 360
360 - 134-130 = 96
x = 96
Answer:
b) $4.60
Step-by-step explanation:
a)
2 panels at $923.40 each = $1846.80
Total with installation: $1944.80
Installation $1944.80-$1846.80 = $98
b)
2 panels at $940.50 each = $1881.00
Total with installation: $1983.60
Installation $1983.60-$1881.00 = $102.60
Substract a from b
102.60-98 = 4.60
Answer:
x=0
Step-by-step explanation:
since 7^0 = 1, it won't affect it any way, meaning it would be 7^8 * 1 aka just 7^8
A literal equation is an equation where variables represent known values. Literal equations allow use to represent things like distance, time, interest, and slope as variables in an equation. You isolate one variable because your goal is to solve for just one variable with respect to others.
