Answer:
.66, 4/5, 84%, .86
Step-by-step explanation:
.66 is already in decimal form.
4/5 converted to decimal form is .8
84% in decimal form is .84
.86 is already in decimal form
Answer:
4 with a remainder of 1
Answer:
Step-by-step explanation:
1. Solve the equations for x
2. Calculate the corresponding values of y
Insert the values into equation (1)
(a) x = 3
y = 3 - 1 = 2
One point of intersection is (3, 2).
(b) x = -2
y = -2 - 1 = -3
The second point of intersection is (-2, -3).
The diagram shows the intersection of the two graphs.
Answer:
(-2,-3) and (3,2)
Step-by-step explanation:
sub in x-1 into y
x^2 + (x-1)^2 = 13
x^2 + (x-1)(x-1)=13
x^2 + x^2 -2x +1 = 13
2x^2 -2x-12=0
solve for x by factoring (quadratic formula, product sum etc..)
x= -2 and 3
plug in those values into y=x-1 and solve for y
The number of pens in each bag if Adams puts 3/4 of a bag of pens in 3 boxes is of a bag.
Given that:
Adams puts a fraction of of a bag of pens in 3 boxes.
It is required to find the number of pens in each box.
Total number of a fraction of pens available = of a bag
These pens are equally distributed among 3 boxes.
So, each box will have an equal number of pens.
So, the number of pens in each box is:
Take the reciprocal of the second number and the operation becomes multiplication.
Hence, the number of pens in each box is of a bag.

Answer:
2A/h - b =a
Step-by-step explanation:
A=h(a+b)/2
Multiply each side by 2
2A =h(a+b)/2*2
2A=h(a+b)
Divide each side by n
2A/h = h(a+b)/h
2A/h = a+b
Subtract b from each side
2A/h - b =a+b-b
2A/h - b =a
Answer:
((2A)/h)- b=a
Step-by-step explanation:
First get the 2 to the left by multiplying each side by 2. Then, get h to the right by dividing each side by h. Lastly, subtract b from each side.
