Answer:
f=6 and s=18
Step-by-step explanation:
Let's solve your system by substitution.
s+f=24;s=3f
Rewrite equations:
s=3f;f+s=24
Step: Solves=3ffor s:
s=3f
Step: Substitute3fforsinf+s=24:
f+s=24
f+3f=24
4f=24(Simplify both sides of the equation)
4f
4
=
24
4
(Divide both sides by 4)
f=6
Step: Substitute6forfins=3f:
s=3f
s=(3)(6)
s=18(Simplify both sides of the equation)
Answer:
f=6 and s=18
I think it could be any 2 in between because it says greater than Luke's decimal which is .20 and less than Bekkas decimal which is .30
Answer:
400 square yards
Step-by-step explanation:
square part = l x w = 20 x 15 = 300
triangle part = 1/2 b x h = 1/2 (20) (10) = 100
300 + 100 = 400
Answer:
22.5°
Step-by-step explanation:
it's a right angle which equals 90°
which is 4 times as much as x
so i just divided 90 by 4
however since you are using formulas it would be written
90 ÷ 4 = x
Answer:
The output of the function y = -6x + 8 when the input is x = 20 is -112.
Step-by-step explanation:
y = -6x + 8
Input the value x = 20.
y = -6(20) + 8
Multiply -6 and 20.
y = -120 + 8
Add -120 and 8.
y = -112.
