Answer:
Step-by-step explanation:
You can simplify this, but not "solve" it. Subtracting 5 from both sides yields
-3x + 6y = -2.
You could graph this easily by finding the x- and y-intercepts. To find the x-intercept, set y = 0: -3x + 6(0) = -2. Then x = 2/3 and the x-intercept is (2/3, 0).
To find the y-intercept, set x = 0: -3(0) + 6y = -2, or y = -1/3 => (0, -1/3)
Plot these two intercepts and draw a line through them.
Select the correct answer. If a six-sided die is rolled 30 times, how many times can you expect to get a 6?
Answer:
5
Step-by-step explanation:
6 over 30 simplify it and boom (divide 30 by 6)
Answer:
If you rolled a six-sided die and rolled it 30 times you would have expected an 6 about 5 times so your answer would be B.

wants to leave a 15% tip for her hairdresser. How
much should she leave for the tip?
Answer:
$6.60
Step-by-step explanation:

44 * .15 = 6.60
There are 500 students in a school. Sara asked 100 of the students what their favorite lunch is. Out of the students surveyed 45 said pizza, 15 said burritos, 30 said hamburgers, and 10 said hot dogs. Based upon the results, how many students out of the whole school should want the items listed? (Round to the nearest whole number.) Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50 Pizza: 22500 Burritos: 7500 Hamburgers: 15000 Hot Dogs: 5000 Pizza: 125 Burritos: 125 Hamburgers: 125 Hot Dogs: 125 Pizza: 45 Burritos: 15 Hamburgers: 30 Hot Dogs: 10
Answer: Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50
Step-by-step explanation:
Since Sara asked 100 of the students for their favorite lunch but there are 500 students in a school, this means that the items listed will have to be multiplied by 5 (500/100) in order to get the number of students in the whole school that'll need the items listed. This will therefore be:
Pizza = 45 × 5 = 225
Burritos = 15 × 5 = 75
Hamburgers = 30 × 5 = 150
Hot dogs = 10 × 5 = 50
The correct option is A:
Pizza: 225 Burritos: 75 Hamburgers: 150 Hot Dogs: 50

x-2y=4 in slope intercept form
Answer:
y = 1/2x - 2
Step-by-step explanation:
Slope intercept form:
y = mx + b
x - 2y = 4
-2y = -x + 4
2y = x - 4
y = 1/2x - 2
3x+6=21 what is the value of x
Answer:
[tex]3x + 6 = 21 \\ 3x = 21 - 6 \\ 3x = 15 \\ x = \frac{15}{3} \\ x = 5[/tex]
Answer: x=5
Step-by-step explanation:
step 1:
put all the coefficients on one side and all the variables on the other, 3x=21-6
step 2: solve the sides, 3x=15
step 3: divide, 3x/3= 15/3
step 4: simplify: x=5

Triangle ABC has vertices A(1,4), B(-1,5), and C(1,-4). Triangle ABC is dilated and
B' is located at (-3,15). What is the y-coordinate of C'?
Answer:
-12
Step-by-step explanation:
The coordinates of B' are just 3 times the coordinates of B, so the multiplier in the dilation is 3.
C' is the point with coordinates 3 times the coordinates of C, making C'(3, -12).
The y-coordinate is -12.

Abbie opened a no-interest bank account with $20, and she deposits $14.50 every week. Carlos opened a no-interest bank account with $28, and he deposits $12.50 every week. Carlos and Abbie do not make any withdrawals from their accounts. The equation below can be used to find w, the number of weeks it will take for the balances in their accounts to be the same. 20 + 14.50w = 28 + 12.50w What value of w makes this equation true?
Answer:
4 weeks
Step-by-step explanation:
14.50 (4) + 20= 78
12.50 (4) + 28= 78

Which expression can be used to represent the 9 more than the quotient of 14 and 2? (14 + 2) ÷ 9 14 ÷ 2 X 9 (14 X 2) + 9 (14 ÷ 2) + 9
Answer:
The expression that can be used to represent 9 more than the quotient of 14 and 2 is (14 ÷ 2) +9
Step-by-step explanation:
The statement 9 more than the quotient of 14 and 2 means
9 + the quotient of 14 and 2.
Now, for the quotient of 14 and 2
Recall that,
Dividend ÷ Divisor = Quotient.
Here, Dividend = 14 and the Divisor is 2
Hence, the quotient of 14 and 2 can be represented by 14 ÷ 2
∴ The statement 9 more than the quotient of 14 and 2 becomes
9 + (14 ÷ 2) OR (14 ÷ 2) +9
Hence, the expression that can be used to represent 9 more than the quotient of 14 and 2 is (14 ÷ 2) +9
These four numbers are plotted on a number line: -2/3, 5/8, -3/5, and -1/2. Which is the correct ordering on the number line from left to right?
A. -1/2, -3/5, 5/8, -2/3
B. -3/5, -2/3, -1/2, 5/8
C. -2/3, -3/5, -1/2, 5/8
D. -1/2, -3/5, -2/3, 5/8
Answer:
-2/3 ; - 3/5 ; - 1/2 ; 5/8
Step-by-step explanation:
Given that:
We could convert the numbers to decimal to obtain a better view of the values :
-2/3 = - 0.66666
5/8 = 0.625
-3/5 = - 0.6
-1 /2 = - 0.5
Negative values are always arranged first on left of a number line.
-0.66666 < - 0.6 < - 0.5 <0.625
Hence,
-2/3 ; - 3/5 ; - 1/2 ; 5/8

First you would need to divide 2688 and 64 you would get 42. Then, now you need to add 64+64+42+42. Which in the end equals 212.
solve for a
2a+3b=12-2(2b+a)
PLEASE SHOW WORK ILL MARK BRAINLIEST.
Answer:
a = 3 - (7/4)b
Step-by-step explanation:
Start by performing the indicated multiplication:
2a+3b=12-2(2b+a) => 2a+3b=12 - 4b - 2a
Next, combine like terms: 4a + 7b = 12
Isolate 4a by subtracting 7b from both sides:
4a = 12 - 7b
Finally, divide both sides by 4:
a = 3 - (7/4)b
