Answer:
y=9
Step-by-step explanation:
-2y + 6 = -12
-2y - 6 = -6
-2y = -18
-2/y= -18/-2
y= 9
You need to subtract six one both sides first, that will cancel out the positive six, and that will also give you this:
-2y = -18
Now, divide negative two on both sides, that will cancel out both the negative signs, and it will also cancel out the two and it will give you your final answer:
y = 9

Sandy orders 20 bread rolls for her party, and 3/5 of the rolls are whole wheat. What other fraction represents the part of rolls that are whole wheat?
Answer:
12/20
Step-by-step explanation:
Sandy orders 20 bread rolls for her party, and 3/5 of the rolls are whole wheat. What other fraction represents the part of rolls that are whole wheat?
The number of rolls that are whole wheat is calculated as:
3/5 × 20 bread rolls
= 12 wheat bread rolls
Hence, the other fraction thag represents the part of rolls that are whole wheat = 12 wheat bread rolls/20 bread rolls
= 12/20
What is the value of 3ab + c when a = 0.32, b = 0.45, and c = 7.2?
Answer:
7.632
Step-by-step explanation:
When solving this equation, you need to substitute the number equal to a where the a is in the equation, along with the b and c. So since a=0.32, then I would put that where the a is in 3ab+c. Same goes with the other letters.
a = 0.32
b = 0.45
c = 7.2
3ab+c
3(0.32)(0.45)+7.2 *Multiply the 3 to 0.32
0.96(0.45)+7.2 *Multiply the 0.96 to 0.45
0.432+7.2 *Add
7.632

Ben deosites 4580 in an account that earns 6% apr compounded weekly. What is the ending balance after 2 years
Given:
Principal value = 4580
Rate of interest = 6% apr compounded weekly
To find:
The total amount after 2 years.
Solution:
The formula for amount is
[tex]A=P\left(1+\dfrac{r}{100n}\right)^{nt}[/tex]
Where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.
1 year = 52 week
n=52
Putting P=4580, r=6, n=52, t=2 in the above formula, we get
[tex]A=4580\left(1+\dfrac{6}{100(52)}\right)^{52\times 2}[/tex]
[tex]A=4580\left(1+\dfrac{6}{5200}\right)^{104}[/tex]
[tex]A=4580\left(1+\dfrac{3}{2600}\right)^{104}[/tex]
[tex]A=4580\left(\dfrac{2603}{2600}\right)^{104}[/tex]
On further simplification, we get
[tex]A=4580(1.1274188)[/tex]
[tex]A=5163.5781[/tex]
[tex]A\approx 5163.58[/tex]
Therefore, the ending balance after 2 years is 5163.58.

The solution of the linear equations will be (1, 1, 2). Then the correct option is A.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The equations are given below.
2x - y - z = -1 ...1
3x + y - z = 2 ...2
x + y - 5z = -8 ...3
Add equations 1 and 2, then we have
5x - 2z = 1 ...4
Add equations 1 and 3, then we have
3x - 6z = -9 ...5
From equations 4 and 5, then we have
15x - 3x = 12
12x = 12
x = 1
From equation 4, then we have
5(1) - 2z = 1
2z = 4
z = 2
From equation 1, then we have
2(1) - y - 2 = -1
y = 1
The solution of the linear equations will be (1, 1, 2). Then the correct option is A.

9514 1404 393
Explanation:
Part A.
1. You have provided an estimate of 600 minutes per month.
__
2. The cheapest plan is likely to be Plan 6 (Public Mobile), as it has no per-minute charge.
__
Part B.
1. Table 2.
See the first attachment for Table 2. For the chosen plan, there is no per-minute charge, so the monthly charge is the same for all numbers of minutes.
__
2. Rate of Change and Slope (m)
a) Adding a minute adds $0 to the cost
b) The rate of change (m) is 0/1 = 0 (dollars per minute)
__
3. Initial value (b)
a) The plan costs $24.00 when no minutes are used.
b) The initial value (b) is 24.
__
4. Equation of the line
a) Filling the found values of m and b into the equation of the line, we have ...
y = mx + b
y = 0x + 24
y = 24 . . . . . . simplified
__
Part C.
Table 3 can be found in the second attachment.
The b in each case is the value from the Monthly Cost column of Table 1.
The m in each case is the value from the Cost per minute column of Table 1.
The equation is found by copying the values of m and b into y = mx + b.
The number in the last column is found by multiplying the minutes (x) by m, then adding b. For example, your cost for Plan 5 (BELL) is ...
y = 0.10x + 10
y = (0.10)(600) +10 = 60 +10 = 70

Solve the equation for p, then justify your reasoning. -9p - 17 = 10
Answer:
p=-17/9 or p=-1.8889
Step-by-step explanation:
-9p-17=10
add 17 to each side
-9p-17+17=10+17
-9p=17
divide both sides by -9
-9p/-9=17/-9
p=-17/9
or p=-1.8889
Solution of equation - 9p - 17 = 10 is p = -3.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given equation
- 9p - 17 = 10
Add 17 to both sides
- 9p - 17 + 17 = 10 + 17
Adding the numbers
- 9p = 10 + 17
Adding the numbers
- 9p = 27
Divide both sides by - 9
-9p/ - 9 = 27/ - 9
Cancel terms that are in both the numerator and denominator
p = 27/ - 9
Divide the numbers
p = -3
Hence, p = -3 is the solution for equation - 9p - 17 = 10

a rectangle has a length 3 meters more than three times the width. the area of the rectangle is less than 90 meters squared. write an expression that represents all possible widths (use the variable x) of the rectangle. write your answer as an inequality, a < x < b.
Answer: -6<x<5
Step-by-step explanation:
Given
Length is 3 m more than three times the width
Suppose width is x
So, the length is 3x+3
The area of a rectangle is [tex]length\times width[/tex]
Area= [tex](3x+3)x<90[/tex]
[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]
