Step-by-step explanation:
I think it is meant to use "j" for Jahiem's age.
so,
j + s = 21
j = s + 7
=> s + s + 7 = 21
=> 2s + 7 = 21
=> 2s = 14
=> s = 7
=> j = s + 7 = 7 + 7 = 14
Examples:
3 x 2 = 6
7 x 2 = 14
Both are greater than 2 .
Counter examples:
1 x 2 = 2
-6 x 2 = -12
Not greater than 2 .
The area for the square is given, and it is 36. To simply find the length of each side, all you have to do is take the area and square root it. The square root of 36 ( ask yourself what number times itself is equal to 36? To get your answer or input it in the calculator. ) is 6. So, the answer is 6 and each side of the quilt is a length of 6.
Answer:
90.8 m
Step-by-step explanation:
Pythagorean Theorem
A²+B²=C²
slant height = C
A = 19.6/2=9.8m
90.9 in to m = 2.3m
9.8²+B²=2.3²
B²=90.9²-2.3² = 8257.52
B=
= 90.8
Answer:
15
Step-by-step explanation:
H - 7
When H = 22, replace H with 22 in the equation.
22 - 7 = 15
