Which expression is equivalent to |b|>7 ? b 7 b 7 b > –7 and b –7 or b < 7
Answer:
b > –7 or b < 7
Step-by-step explanation:
The number of days, d, that it will take to build a house is given by
d= 720 divided by n
where n is the number of workers used each day.
Ali's company will take 40 days to build the house.
Hayley's company will take 30 days to build the house.
Hayley's company will have to use more workers each day than Ali's company.
How many more?
Answer:
6 more workers
Step-by-step explanation:
The relationship between days (d) and number of workers (n) is given by the equation;
d = 720 / n
Ali's company will take 40 days to build the house.
n = 720 / d
n = 720 / 40 = 18 workers
Hayley's company will take 30 days to build the house.
n = 720 / d
n = 720 / 30 = 24 workers
Hayley's company will have to use more workers each day than Ali's company.
How many more?
24 - 18 = 6 more workers

Find all real square roots of -36
Answer:
The answer is ±6.
Step-by-step explanation:
The positive and negative square roots of 36 are 6. and −6. Both 6, and −6 are square roots of 36 since they both give 36 when squared:...
6^2=6×6=36
(−6)2=(−6)×(−6)=36
All positive real numbers have a positive and negative real square root which are additive inverses of one another.
The principal square root is the positive one and is the one meant when we use the √... symbol. So:...
√36=6
If we want to refer to the negative square root, then just put a minus sign in front:...
−√36=−6
The two square roots of -36 are 6i and -6i, where i is the imaginary unit.
What is Number system?A number system is defined as a system of writing to express numbers.
Since the square of any real number is always non-negative, there is no real number whose square is equal to a negative number.
Therefore, the expression √(-36) has no real square roots.
However, we can express the square root of -36 using imaginary numbers.
By definition, the imaginary unit "i" is equal to the square root of -1. Using this definition, we can rewrite √(-36) as:
√(-36) = √(36) × √(-1) = 6i
Therefore, the two square roots of -36 are 6i and -6i, where i is the imaginary unit.

Fill in the other values of y the same way.
Answer:
(-4, -6)(-3, -4)(-2, -2)(-1, 0)(0, 2)(1, 4)(2, 6)Explanation:

y = 2(-4) + 2
y = -6
x: -3y = 2(-3) + 2
y = -4
x: -2y = 2(-2) + 2

1/3 of Cheryl’s savings was the same as 3/4 of Hilda’s savings.Cheryl saved $36.
(a) Find the ratio of Cheryl’s savings to Hilda’s savings.
(b) How much did Hilda save?
Answer:
a) the ratio is 9:4
b) Hilda did save $16.
Step-by-step explanation:
Let's define the variables:
C = Cheryl's savings.
H = Hilda's savings.
We know that:
(1/3)*C = (3/4)*H
We also know that Cheryl saved $36, then we have:
C = $36
Now we can replace that in the above equation to get:
(1/3)*$36 = (3/4)*H
$12 = (3/4)*H
$12*(4/3) = H = $16
Then Hilda did save $16.
And the ratio between of Cheryl's savings to Hilda's savings is:
36 : 16
We can simplify this if we divide both by 2.
(36/2) : 16/2
18 : 8
Again, we can divide both by 2:
(18/2) : (8/2)
9 : 4
Then the ratio is 9 : 4

An iPhone costs £799 in London, €850 in Paris and $970 in New York.

Give your answer to 2 dp.
please answer for heart, comment, 5 star rating, and brainliest
Answer:
£683.10 in New York.
Step-by-step explanation:
Given the following data;
iPhone costs in London = £799
iPhone costs in Paris = €850
iPhone costs in New York = $970
£1 = €1.17 and £1 = $1.42
First of all, to find the cheapest (lowest) price for the three phones we would have to convert the prices to Pounds (£).
a. iPhone costs in London = £799
b. iPhone costs in Paris = €850
To find the price in Pounds (£);
£1 = €1.17
iPhone costs in Paris = €850/€1.17
iPhone costs in Paris = £726.50
c. iPhone costs in New York = $970
To find the price in Pounds (£);
£1 = $1.42
iPhone costs in New York = $970/$1.42
iPhone costs in New York = £683.10
Therefore, the lowest price for the iPhone is £683.10
y -3 = x
Pls explain thank u so much!!
Answer:
Y = x+3
Step-by-step explanation:
You want to start by figuring out how to get Y alone.
So to get it alone so you add +3 on both sides
Y - 3 = x
+3. +3
Positive 3 and Negative 3 cancel out making it zero.
Visual: 3 - 3 = 0
Since you cant take or add anything from x you leave it as + 3 so the answer should be.
Y = x + 3
