Answer:
-3
Step-by-step explanation:
3×b or 5=15
2×c or-3=-6
3×-6=-18
15-18=-3
Answer:
33
Step-by-step explanation:
What is the value of 3(b-2c) if b is 5 and c is -3?
Well, we know that b=5 and c=-3. We can go ahead and plug this in into the expression.
3[5-2(-3)]
Following the rules of PEMDAS, we multiply the 2 and -3, which results in -6.
3[5-(-6)]
5-(-6)= 5+6= 11, then it will leave use with:
3(11).
3x11=33, which is our final answer.
Could someone pls help me with this :)

if the line passes through the top left part AND the bottom left part, slope's positive. if it passes through both of the other ones slope is negative. if it's parralell to one of the axis, the answer is undefined or 0, the horizontal one being 0
right away we can see line b's slope is positive, and line d's slope is negative.
y=mx+b
b is the y intercept
m is slope

On an architect’s drawing of a house, 1 inch represents 1.5 feet. If the bedroom window is 5 inches long on the drawing, how many feet long will it be in the actual house?
Brainliest if you answer
Answer:
3.33~
Step-by-step explanation:
Since 1 inch represents 1.5 feet, you'll divide 5 inches by 1.5. And get 3.33 repeating
Answer:
7.5 feet
Step-by-step explanation:
REASONAccording to the given scale, 1 inch on the drawing represents 1.5 feet in the actual house.
Therefore, to find the length of the bedroom window in feet, we need to multiply the length on the drawing (5 inches) by the scale factor (1.5 feet/inch):
5 inches * 1.5 feet/inch = 7.5 feet
Hence, the bedroom window will be 7.5 feet long in the actual house.

A recipe for chocolate chip cookies requires 6 cups of flour. This recipe serves 24 people, and you would like to make enough for 36 people. How many cups of flour do you need?
Anyone know the steps to solve it?
Answer:
9 cups
Step-by-step explanation:
You divide 24 by 6 and get 4 then divide 36 by 4 and get 9.
Answer:
9 cups.
Step-by-step explanation:
i didnt solve the question how a teacher would want you to solve it but who cares this is how i solved it:
so you need to find how many more people you would be servering so 36-24 which equals 12. so your serving 12 more people than in the original recipe. 12 happens to be half of 24 which is the amount of people the recipe servers, so that means you need to add half of what you need in the normal recipe so half of 6, which is 3. so then you 6+3 which equals 9.
Follow the steps to find the quotient.
8/328
Answer:
41
Step-by-step explanation:
8 can go into 32 4 times so the first number is 4.
Then 8 can go into itself once so that's 1, and you'll get 41

Answer:
2b+24x
Step-by-step explanation:
Hey There!
So for this problem all we have to do is combine like terms
The like terms for this problem would be (7b and -5b) and (3x and 21x)
7b-5b=2b
3x+21x=24x
So the expression simplified would be equal too 2b+24x

the area, a, of a trapezoid is given by the formula a=1/2h(c+d), where h is the height and c and d are the lengths of the bases rearrange the formula so that the height h of the trapezoid can be determined given the area and the lengths of the bases enter your answer in the box
Answer:
this is algebra remember algebra rules and thing really hard
Step-by-step explanation:
The formula for the height of the trapezoid will be h = 2A/(c+ d).
What is surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.
Given a trapezoid with side lengths c and d and perpendicular distance as h
So, the area formula will be
A = (1/2)h(c + d)
Multiply both sides by 2
2A = h (c + d)
Divide by c + d into both sides
2A/(c + d) = h
Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".

Sara’s boss informed her she is getting a 5% raise. She currently makes $22 per hour. What is her new hourly wage?
Use your plan of multiplying 5100 and $22. What is the amount of Sara's raise?
Answer:
Her new hourly wage will be $23.10
Step-by-step explanation:
First, let's find out how much her raise is in dollars.
0.05 x 22 = 1.10
Then, let's add that to her current wage.
1.10 + 22.00 = $23.10
Hope this helps! Have a great Monday!
Answer:
Her new hourly wage will be $23.10
Step-by-step explanation:
5/100 * 22= 1.1
1.1 + 22= 23.1
