Answer:
a) Veronica earns $276. Francis earns $216
b) $6000
Step-by-step explanation:
Veronica's income would be I= 0.035s +150 where I is income and s is sales while Francis's income would be 0.06s. So for $3600 in sales Veronica earns $276 while Francis earns $216. To find the answer to part b just set the two equations equal to each other and solve for x. so 0.035x + 150 = 0.06x Subtracting 0.035 x from both sides gives 150 = 0.025x. Dividing both sides by 0.025 gives x = $6000
Let x be the length of the garden
and y be the width of the garden.
since you only enclose 3 sides of the garden by a 40 ft fence. so the equation for this is:
2x + y = 40
and the area of the garden is 100 sq ft, so in equation
xy = 100
from equation 1, 2x + y = 40
y = 40 - 2x
substitute to equation 2
xy = 100
x ( 40 - 2x) = 100
40x - 2x^2 = 100
2x^2 - 40x + 100 = 0
x = 2.9 ft
y = 34.5 ft
Subtract final value minus starting value.
Divide that amount by the absolute value of the starting value.
Multiply by 100 to get percent increase.
If the percentage is negative, it means there was a decrease and not an increas
Answer:
section 4.4 are the answer choices?
Step-by-step explanation:
Answer:
x=−11
Step-by-step explanation:
7+5(x−3)=7(x+2)
Step 1: Simplify both sides of the equation.
7+5(x−3)=7(x+2)
7+(5)(x)+(5)(−3)=(7)(x)+(7)(2)(Distribute)
7+5x+−15=7x+14
(5x)+(7+−15)=7x+14(Combine Like Terms)
5x+−8=7x+14
5x−8=7x+14
Step 2: Subtract 7x from both sides.
5x−8−7x=7x+14−7x
−2x−8=14
Step 3: Add 8 to both sides.
−2x−8+8=14+8
−2x=22
Step 4: Divide both sides by -2.
−2x
−2
=
22
−2
x=−11
