Answer:
2x - 5 = 7
2x -5 + 5 = 7 + 5
2x = 12
2/2x = 12/2
x = 6
Step-by-step explanation:
I think that 0.45 would be one.
Answer:
21/26
Step-by-step explanation:
In the simplest categorization, English has 26 alphabets. Out of which, 5 are vowels and rest 21 are consonants.
so the fraction would be 21/26
Answer:
A. square root of a^2 + b^2 for both answers
Step-by-step explanation:
The first problem, we are given
a^2 + b^2 = c^2
What we do is solve for c.
sqrt(a^2 + b^2) = c
c = sqrt(a^2 + b^2)
For problem 2,
WE can apply the Pythagorean theorem because we have a right triangle.
The equations is
a^2 + b^2 = c^2 like the first problem
Solving gets us
sqrt(a^2 + b^2) = c
c = sqrt(a^2 + b^2)
Answer:
56 in
Step-by-step explanation:
Square ....so each side is = x
x * x = area = 196
x^2 = 196
x = sqrt (196) = 14 in
perimeter = x + x + x + x = 56 in
