Answer 1

Answer:

The value of z in the following equation 2(4z − 9 − 7) = 166 − 46 is 19. Details about solving equations can be found below.

How to solve algebraic expressions?

An algebraic equation is a mathematical equation in which one or both sides is an algebraic expression, such as 2x + 7y = 3.

The following algebraic equation is given in this question; 2(4z − 9 − 7) = 166 − 46. The value of z can be calculated as follows:

8z -18 - 14 = 120

8z - 32 = 120

8z = 152

z = 152/8

z = 19

Therefore, the value of z in the following equation 2(4z − 9 − 7) = 166 − 46 is 19.

Answer 2

Answer: 2(4z-9-7)=166-46 well, perentices (however u spell these things) first, -9-7 = -16 so 2(4z-16)=166-46 and distributive property so 8z-32=166-46, 166-46 = 120, so 8z-32=120, add 32 to both sides, which would be 8z=152 divide both by 8, z=19

Find the quotient of 5/31 divided by 15/23. Reduce your answer to the lowest fraction

The answer for dividing 5/31 by 15/23 is 23/93

What is division of fractions?

The division of fractions means dividing a fraction into further equal parts.

For example, If you have three-fourth of a pizza left, and you divided each slice into 2 parts you would get a total of six slices, but this would represent six-eighths of the total pizza.

Given that, find quotient 5/31 divided by 15/23.

5/31÷15/23

We know that, when we divide two fractions, we do the reciprocal of the second fraction and multiply it by the first fraction,

5/31×23/15

= 23 / 93

Hence, the answer for dividing 5/31 by 15/23 is 23/93

Answers

Based on the results, the chance that a random donor has type A blood is; 11/25

How to find the Probability?

We are told that there was a survey of 75 blood donors.

Now, we want to find the chance that a random donor has type A blood. From the given table, we see that there are 33 type A blood donors. Thus;

P(donor has type A blood) = 33/75 = 11/25

What I think the chance that a random donor has type a blood is 44% because there are 33 people in total of 75 that have type A blood type so you simply just divide 33/75 then get .44 which is 44%

Find the width of a rectangle with a perimeter of 90 and a length of 15.A.90
B.15
C.45
D.30
I really need help.

Answers

A rectangle has 2 sets of equal parallel lines. And we know one of the sides is 15.
So we know two of the sides have to be 15. Right?

So that means 15 x 2 = 30

So we know that two of the sides add up to equal 30.

The entire perimeter is 90. Well we've used 30 so lets see how much we have left to use.

90(the entire perimeter) - 30(the amount we know) = 60(what we have left)

So the last two sides of the rectangle equal 60, since there are two sides, let's divide the remaining perimeter by 2

60(both of the sides) / 2(the last 2 sides that we haven't found the length for yet) = 30

So now we know all of the sides.

Let's read the question again now.

"Find the 'WIDTH' of a rectangle with a perimeter of 90 and a 'LENGTH' of 15"

So it's 15 long(length), and 30 wide(width)

If this doesn't help, I can draw a picture and it mights make some more sense :)

Final answer:

The width of the rectangle is 30 units.

Explanation:

To find the width of a rectangle, we need to use the formula for the perimeter of a rectangle, which is 2(length + width). In this case, we are given the perimeter as 90 and the length as 15. Plugging these values into the formula, we get: 90 = 2(15 + width).

Now we can solve for the width. First, simplify the equation: 90 = 30 + 2(width).

Then, subtract 30 from both sides: 60 = 2(width). Divide both sides by 2 to isolate the width: width = 30.

Therefore, the width of the rectangle is 30 units.
