simplify 3c x 5c
show working out
Answer:
15c
Step-by-step explanation:
3c x 5c =
3 x 5= 15
15c
the easiest way to do this problem is take away the c's in the expression and add them to your answer at the end which you would just be multiplying 5 x3 which = 15 then you would put the c next to the 15 so the answer would be 15c

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mo walked 12 miles in 3 hours.
In 1 hour Mo walked= 12/3
= 4 miles
and, in 5 hours Mo walked
= 5 x 4
= 20 miles.
Hence, Mo walked 20 miles in 5 hours.

I don’t get this please help me if your smart u get 10 points
Answer:
112
Step-by-step explanation:
Supplementary angles means that angle A and angle B added together equal 180˚. This mean we can re-write the angle measures into an algebra problem
A(3x+16) + B(2x + 4 ) = 180
Or
5x + 20 = 180
5x + 20 - 20 = 180 - 20
5x = 160
5x/5 = 160/5
x = 32
Now that we know that X = 32, we can plug 32 into the measure of angle A.
A(3x+16)
A(3(32)+16)
A(96+16)
A(112)
Angle A equals 112˚ and Angle B equals 68˚.
4(x+2) + 2x = 44
solve for x
Answer:
x = 6
Step-by-step explanation:
4(x + 2) + 2x = 44
~Distribute left side
4x + 8 + 2x = 44
~Combine like terms
6x + 8 = 44
~Subtract 8 to both sides
6x = 36
~Divide 6 to both sides
x = 6

help plz answer all no need for expaninations
Answer: C, B, A, D
Step-by-step explanation:
1. option C
f(x) = 2x² - 1
f(-1) = 2(-1)² - 1
= 2(1) - 1
= 2 - 1
= 1
2. option B
f(x) = 2x - 5
11 = 2x - 5
16 = 2x
8 = x
3. option A
f(x) = 2x - 5
f(3) = 2(3) - 5
= 6 - 5
= 1
4. option D
f(x) = x² + 7
f(-2) = (-2)² + 7
= 4 + 7
= 11

Assume that the distance from Earth to the moon is exactly 238,855 miles and that it took astronauts 75 hours to reach the moon in 1969. How far did the astronauts travel each hour, on average, during their trip to the moon?
Answer: They traveled 3,184.733333333333
Step-by-step explanation: Do 238,855 divided by 75 (The three keeps going on forever).
mark the other guy brainliest because he is correct it is B or 3,184.73 (the 3 has a line over it)

Your mother bought several full packets of eggs. She opened all the packs and kept all the eggs in the fridge. You later counted all the eggs and found there are 46 eggs. One single packet looks as shown below. Do you think shopkeeper cheated your mother? Justify.
Answer:
Even when the answer is not complete, most likely yes, she was cheated.
Step-by-step explanation:
The question does not include how a packet looks, however since the total egg count is 46 units, this number is only divisible by 2 and 23.
So unless each egg packet contains 2 or 23 eggs, any other size would mean a packet had less eggs than expected.
Usually eggs come in packs of 6 or 12 units, so to sum 46 eggs or more you would need:
If 6 eggs per packet:
46/6 = 7,66 packets -> she must have bought 8 packets and should have 48 eggs, meaning there are 2 eggs missing.
If 12 eggs per packet:
46/12 = 3,83 packets -> she must have bought 4 packets and should have 48 eggs, meaning there are 2 eggs missing.
That's why it is safe to assume some packets had less eggs than expected.

Step-by-step explanation:
The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weight of the crackers in the boxes. What is the weight, in ounces, of one box? 11 ounces per box 12 ounces per box 15 ounces per box 16 ounces per box
Answer:
15 ounces per box
Step-by-step explanation:
What is the weight, in ounces, of one box?
165ounces/ 11 boxes
This means
165ounces per 11 boxes
Hence:
11 boxes = 165ounces
1 boxes = x ounces
Cross Multiply
11x = 165 × 1
x = 165/11
x = 15 ounces
Therefore, the weight, in ounces, of one box is 15 ounces per box.
Answer:
15 ounces per box

Which line is perpendicular to y = 4x + 5?

Factor x^2+x-12 = 0 and x^2-6x+9 = 0.
Answer: x^2+x-12 = 0 ⇒ x = -4 or x = 3 and x^2-6x+9 = 0 ⇒ x= 3
x^2+x-12 = 0 (Find two numbers that add to 1 and multiply to -12)
x^2-3x+4x-12 = 0 (Factor out like terms)
x(x-3)+4(x-3) = 0 (Group common terms)
(x-3)(x+4) = 0 (Set each term to equal 0 and solve for x)
∴ x = -4 or x = 3
x^2-6x+9 = 0 (It's a perfect square trinomial)
(x-3)^2 = 0
∴ x = 3
Answer: x = -4 and x = 3 for the first one. x- 3 for the second one.
