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
Answer:
Usually it means to solve it. Sometimes they give you values to substitute in for variables (letters) in the math sentence/equation/expression.
Does that make sense?
Step-by-step explanation:
The two angles are corresponding angles, which means they are equal to each other. Make them equal to each other in an equation.
11x - 2 = 130
Add 2 to both sides.
11x = 132
Divide both sides by 11.
x = 12
if y-6 > 10, and 16-6 = 10, then y > 16 since 17-6 = 11, which is greater than 10. Any number greater than 16 can fulfil this inequality.
Answer:
3000 cm³
Step-by-step explanation:
Volume = Difference of Volumes of the two pyramids
Volume, V1, of the larger pyramid with tip at L:
Base area = area of EFGH = 10²
Height = ML = 15
V2 = ⅓×(10²)×15 = 4000
Volume, V2, of the smaller pyramid with tip at L:
Base area = area of = 10²
Height = OL = OM+ML = 15+15 = 30
V1 = ⅓×(10²)×30 = 1000
Volume = V1 - V2
= 4000-1000 = 3000 cm³
