Becky is working on a weekly budget. She earns $385 per week. Becky spends $200 per week on rent and utilities plus $57 on food. After paying for rent, utilities, and food, Becky deposits 3/4 of the amount left over into a savings account. She spends the rest on entertainment. How much money does she spend on entertainment?
Answer:
$32
Step-by-step explanation:
200 + 57 = 257.
385 - 257 = 128
128 x 3/4 = 96 (deposited)
128 - 96 = 32
Becky spends $32 on entertainment

Samantha fills her car's gas tank. It now has 18 gallons of gas. She uses 1/2
of the gas when she drives to the beach. Then, she uses 3/4 of the
remaining gas when she drives to the mall. How many gallons of gas does
Samantha's car have left? *
Answer:
18 x 1/2 = 9
18 - 9 = 9
9 x 3/4 = 27/4
9 - 27/4 = 2 1/4 or 2.25 gallons

help me on the following, in the picture IK U WANT THE POINTS JUST HELLPPP , ONLY IF UKNOW THE ANSWER/ NO LINKS and swrong answers
Answer:
any coordinate outside the parabola is a reasonable answer.
Step-by-step explanation:
test the solution (0, 0) and if if that number is greater than 0 then the rest of the points outside on the inside are.
x = 0
y = 0
(0)^2 - 2(0) - 3 = -3
-3 is less than 0 so (0, 0) is not a possibility so any coordinate outside the parabola is a reasonable answer.

Which of the following is a binomial with degree 2?
A: 2+5x-3x^3
B: 2xy^2
C: 2x^3+xy
D: 3x+3x^2
Answer:
D
Step-by-step explanation:
Binomial means that it will have two terms, so by process of elemination, we are only left with C and D. Degree would be the power, and D is the only one that has a power of 2.

Answer:
x = 5.
y = -2
Step-by-step explanation:
y = x - 7
2x + y = 8
substitute the first equation into the second
2x + (x -7) = 8
2x + x - 7 = 8
3x - 7 = 8
3x = 8 + 7
3x/3 = 15/3
x = 5.
substitute 5 in the second equation
y = 5 - 7
y = -2
Please help!!! What is the equation of the line in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = x - 40
Step-by-step explanation:
Points on the graph: (0, -40) and (60,20)
Slope:
m=(y2-y1)/(x2-x1)
m=(20+40)/(60-0)
m=60/60
m = 1
Slope-Intercept
y - y1 = m(x - x1)
y + 40 = 1(x -0)
y + 40 = x
y = x - 40
Answer:
y=-x-40
Step-by-step explanation:Slope intercept form is y=mx+b
slope=rise/run
slope= -40/40 = -1
y-y1=m(x-x1)
y-(-40)= -1(x-0)
y+40=-x+0
y=-x+0-40
y=-x-40
hope that helps?

George and carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 350 miles in total, and they biked 80 kilometers more than they were bused.
Complete question − How many kilometres did they travel by bus and by bicycle.
Answer:George and carmen traveled by bus in 135km and by bikein 215km
Step-by-step explanation:
Total Miles traveled = 350 miles
Let Number of kilometres they traveled with bus = x
and Let Number of kilometres they traveled with bike = x + 80
so that the total distance traveled with bus and bike be expressed as
x + x + 80 = 350 miles
2x + 80 = 350 miles
2x = 350 − 80
2x =270
x=135
George and Carmen traveled by bus in 135km
and by bicycle=x + 80 = 135 km + 80 =215km

A physician is testing the effectiveness of wo new exercise plans on 70 subjects. To assign the subjects to the two treatment groups, he writes "Plan 1" on one stip of paper and "Plan 2" on another slip of paper. He randomly picks one of the slips, and assigns the first 35 subjects who signed up to that plan, and assigns the last 35 subjects to the other plan. Select the statement that best describes the composition of the treatment groups.
The treatment groups might not be comparable, because there is not a control group
The treatment groups should be comparable, because there are a large number of subjects in each group.
The treatment groups should be comparable, because the exercise plan for each group was randomly selected
The treatment groups might not be comparable, because the first 35 subjects to sign up for the study might share a characteristic related to exercise, such as high motivation.

Answer:
X=1.5
Y= -0.5
Step-by-step explanation:
3X+Y=4
Y=4-3X
5X-7Y=11
5X-7(4-3x)=11
5X-28+21X=11
26X=11+28
26X=39
X=1.5
Y=4-3(1.5)
Y=4-4.5=(-0.5)
Answer:
x=1.5 y=-0.5
Step-by-step explanation:
first we want to rearrange one of the equations
we will rearrange 3x+y=4 we will do this by subtracting 3x from both sides
y= -3x+4
and replace y in the second equation 5x-7y=11
5x -7(-3x+4)=11
we will distribute -7
5x+21x-28=11
solve for x
26x=39
x=1.5
and solve y by substituting x into one of the equations
y= -3(1.5)+4
y=-0.5

What is the solution to this system? Solve by substitution. y= 4x +3 and 2x - 3y = 21
Answer:
x= -3
y= -9
Step-by-step explanation:
Y-4X =3 ; 2x-3y=21
Y= 3+ 4x
2x -3( 3+4x)= 21
2x- 9- 12x= 21
-10x -9= 21
-10x -9+9= 21+9
-10x = 30
X= 30/-10= -3
Y= 3+4x = 3+ 4* (-3)= 3-12= -9
