Answer:
Savannah collected 180 stamps and her brother collected 36 stamps
Step-by-step explanation:
Let
x = number of stamps Savannah brother collected
Savannah collected 5 times as many stamps as her brother, then
5x = number of stamps Savannah collected.
Total number of stamps = 216, then
![x+5x=216\\ \\6x=216\\ \\x=\dfrac{216}{6}\\ \\x=36\\ \\5x=5\cdot 36=180](https://tex.z-dn.net/?f=x%2B5x%3D216%5C%5C%20%5C%5C6x%3D216%5C%5C%20%5C%5Cx%3D%5Cdfrac%7B216%7D%7B6%7D%5C%5C%20%5C%5Cx%3D36%5C%5C%20%5C%5C5x%3D5%5Ccdot%2036%3D180)
Answer:
^G=98°
Step-by-step explanation:
So you know that angle x and angle g summed up together make 180°.
^F+^H+^G= 180°
<=> 53°+45°+^G=180°
<=> ^G= 180°-98°=82°
180°-82°=98°

Step-by-step explanation:
the answer to this problem is 14
Answer:
i think your answer is two times the sum of x and seven plus ten
if i am wrong than tell me
Step-by-step explanation:
hope this will help :)
Dimensions:
(x-3)
(x+2)
Perimater = sum of sides:
Perimeter = 14 in
Replacing:
14 in = 2 (x-3) + 2 (x+2)
Solve for x :
14 = 2x-6 + 2x + 4
combine like terms:
14 = 2x+2x-6+4
14 = 4x - 2
14+2 = 4x
16 = 4x
16/4 = x
x = 4
Dimensions:
(x-3) = 4-3 = 1
(x+2) = 4 + 2 = 6
