Any time when the letter and number together and says what is letter equal you must multiply!
For example: a=5
There is a equation and it says what is: 4a
It is the same thing as multiply so what you do is 4x5 since a is equal to 5 then boom, it’s that easy you’re answer is 20.

The area of a rectangular field is 48m2 and one of its sides is 6m . How long will a lady take to cross the field diagonally at the rate of 20m/min
Answers
Answer:
It will take her approximately 28 seconds to cross the diagonal of the pitch
Step-by-step explanation:
If we can find the length of the diameter of the field (in Metres), we can easily find the time it takes her to cross this length using motion equations.
Step one: Find the length of the field from its area.
The field is rectangular in shape. The area of the field is 48m^2. To get the area of the field, we had to multiply its length and its breadth.
i.e area = length X breadth.
Let us assume that the breadth = 6m
its length will be area / breadth = 42/ 6 = 7m
The length of the pitch = 7 m
Step Two: Find the length of the diagonal using Pythagoras' theorem.
From Pythagoras'theorem, the length of the diagonal can be obtained by
[tex]diagonal = \sqrt{l^2 +b^2}[/tex]
[tex]diagonal = \sqrt{6^2+ 7^2} = 9.22m[/tex]
The length of the diagonal is 9.22m
Step three: Find the time using her speed and the distance she needs to cover.
Time = distance / speed
time = 9.22 /20 = 0.46 minutes
It will take her approximately 28 seconds to cross the diagonal of the pitch

The height odf a regtangular pyramid is 4 inches. The base of the pyramid measures 9 inches by 9 inches. What is the volume of the rectagular pyramid in cubic inches?
Answers
Answer:
[tex]V=108\ \text{inches}^3[/tex]
Step-by-step explanation:
Given that,
The height of a rectangular pyramid is 4 inches
The base of the pyramid measures 9 inches by 9 inches.
We need to find the volume of the rectangular pyramid. The formula for the volume of the rectangular pyramid is given by :
[tex]V=\dfrac{lbh}{3}[/tex]
Substitute all the values,
[tex]V=\dfrac{4\times 9\times 9}{3}\\\\V=108\ \text{inches}^3[/tex]
So, the volume of the rectangular pyramid is [tex]108\ \text{inches}^3[/tex].

Answers
Answer:
b = 6
Step-by-step explanation:
Let's solve for b.
(3x−1)2=9x2−bx+1
Step 1: Flip the equation.
−bx+9x2+1=9x2−6x+1
Step 2: Add -9x^2 to both sides.
−bx+9x2+1+−9x2=9x2−6x+1+−9x2
−bx+1=−6x+1
Step 3: Add -1 to both sides.
−bx+1+−1=−6x+1+−1
−bx=−6x
Step 4: Divide both sides by -x.
b = 6

Rearrange to make subject x 4(x-3)/a=y
Answers
Answer:
answer is x = ay + 12/4
Step-by-step explanation:
first we cross multiply on both sides which will give us this
4( x -3)=ay
we then open the brackets by multiplying 4 with x and -3 which gives
4x - 12= ay
then take 12 to the other side
4x - 12+12= ay + 12
4x = ay + 12
divide 4 on both sides
4x /4= ay + 12/ 4
therefore x = ay + 12/ 4

A bag contains only red, green, brown and yellow marbles. The probabilities of selecting each colour are shown below. Colour Red Green Brown Yellow Probability 0.2 0.3 x 0.1 Find the probability of selecting a brown marble.
Answers
Answer:
0.4
Step-by-step explanation:
Given that:
Probability of :
Red _____Green ___ Brown _____ Yellow
0.2 ______ 0.3 ______ X ________ 0.1
Since the bag contains only red, green, brown and yellow marbles ;
The sum of each color's probability should sum up to 1;
ΣP(x) = 1
Hence,
0.2 + 0.3 + x + 0.1 = 1
0.6 + x = 1
x = 1 - 0.6
x = 0.4
P(brown) = 0.4

Gabriel is at the grocery store, and wants to figure out his total cost before he gets to the register. He bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each. Gabriel remembers he has a coupon for $2 off his bill.
Gabriel has $30 to pay for the groceries. What simplified expression would represent the amount of change he should receive
Answers
Answer:
32 - 2.5x - 2y
Step-by-step explanation:
He bought 2.5 pounds weight of apples for x dollars a pound. Thus, cost is 2.5x.
He bought 2 bags of lettuce for y dollars each. Thus, cost is 2y
Total bill cost = 2.5x + 2y
We are told he has a coupon for $2 off his bill.
This means the amount he will pay will now be;
2.5x + 2y - 2
Gabriel has $30 to pay for the groceries.
Thus, his change will be;
30 - (2.5x + 2y - 2)
This gives;
32 - 2.5x - 2y

3/4 (12x+8)=-13- (2x+3)
Answers
Answer: = − 2
Step-by-step explanation:
3/4 (12x+8)=−13−2x−3
Simplify 3/4(12x+8) to 3(12x+8)/4.
3(12x+8)/4=-13-2x-3
Factor out the common term 4.
3x4(3x+2)/4=-13-2x-3
Simplify 3×4(3x+2) to 12(3x+2).
12(3x+2)/4=-13-2x-3
Simplify 12(3x+2)/4 to 3(3x+2)
3(3x+2)=−13−2x−3
Simplify −13−2x−3 to −2x−16
3(3x+2)=−2x−16
Expand
9x+6=−2x−16
Add 2x to both sides.
9x+6+2x=−16
Simplify 9x+6+2x to 11x+6.
11x+6=−16
Subtract 6 from both sides.
11x=−16−6
Simplify −16−6 to −22
11x=−22
Divide both sides by 11.
x=− 22/11
Simplify 22/11 to 2.
x=−2
