Answer:
7 are boys
Step-by-step explanation:
Make a system of equations where g is for girls and b is for boys.
b+g=26
g=3b-2
Substitute "3b-2" in for "g" in the first equation.
b+(3b-2)=26
Rewrite without the parentheses because it's addition and not multiplication.
b+3b-2=26
Combine like terms.
4b-2=26
Add 2 to both sides.
4b=28
Divide by the coefficient of the variable to get it alone.
b=7
If the radius is tripped, the volume will increase by 3^3 = 27 times.
Answer: 27 times
Answer:
It 20.54 round to the nearest tenth which is 20.5
Step-by-step explanation:
Answer: x = 27
Step-by-step explanation:
2x+3x+45=180º because all of the angles of a triangle add up to 180
5x=180-45
5x=135
x=135/5
x=27
1946 times 3/100=58.38
58.38 times 5 =291.9
1946-291.9=165.41
165.41 is the answer. Please mark brainliest.
