Answer:
50j+30 and 5(10j+6)
Step-by-step explanation:
5(7j+6+3j)
First, do the parenthesis
5(10j+6)
Distribute
50j+30
The answer is C. If we want to go on x rides, we need to pay 40+5x dollars at Thrill Park, and 60+3x dollars at Splash Park. The average money needed for each ride is (40+5x)/x at Thrill Park, (60+3x)/x at Splash Park. Therefore, the system of equations is y=(40+5x)/x, and y=(60+3x)/x.
Answer:
2x+8b
Step-by-step explanation:
First since 1 and 8b are on the same side mutiply them:
1bx8=8b
So our new equation is 2x+8b
SOLUTION - GIVEN = Sara has two bag with 60% & 28% peanut.
prove = How much the peanut is used to make 10 pound of 45%
peanut.
TO PROOF - Assume that
let x be the value of the peanut used by sara from the bag
60% peanut bag.
let ( 10 - x) be the value of peanut used by sara from 28% peanut
bag.
as given the bag become of the 10 pound which contain
45% of peanunt.
thus we have
0.60x + 0.28 ( 10 - x ) = 0.45 (10)
0.60x + 0.28 ( 10 -x ) = 4.5
0.60x + 2.8 - 0.28 x = 4.5
0.60x - 0.28x = 4.5 - 2.8
0.32x = 1.7
x = 5.3125 peanut is taken from the 60% bag.
& 4.6875 peanut from the 28% bag.
Answer:
11253.76
Step-by-step explanation:
To find the volume of a cylinder we must utilise the volume of cylinder formula which is
→ Volume of cylinder = π × r² × h
Where 'r' is the radius and 'h' is the height so let's start substituting in the values,
→ Volume of cylinder = π × r² × h
⇒ Substitute in 3.14 for π, 14 for 'h' and 16 for 'r'
→ Volume of cylinder = 3.14 × 16² × 14
⇒ Simplify
→ Volume of cylinder = 11253.76
So a cylinder has a height of 14 millimetres and a radius of 16 millimetres has a volume of cylinder 11253.76 inches³
