Answer:
We can write 7 + 2 + 1 in two different ways.
a)
7 + 1 + 2b)
1 + 7 + 2Step-by-step explanation:
The commutative property of addition states that we can add the numbers in any order and get the same answer.
For example, if we add 'a' and 'b' together, the commutative property of addition states that we would get the same answer whether we add a + b or b+a.
In other words,
a + b = b + 1
In our case, we are given
7 + 2 + 1
According to the commutative property of addition, we can add the number in any order and get the same answer.
Therefore, we can write 7 + 2 + 1 in two different ways.
a)
7 + 1 + 2b)
1 + 7 + 2Verification:
Thus, the answer will remain the same in any order.
i.e.
7 + 2 + 1 = 7 + 1 + 2 = 1 + 7 + 2

Answer:
1) b and m
2) m∠8=m∠6
3) 160°
4)x=60°
Step-by-step explanation:
1) all straight lines sum to 180°
subtract the angles given from 180°
the other angle for b is 25°, while the other angle for m is 155°
so we can see that the angles for both lines are the same, hence they are parallel.
2) ∠8 should be the same as ∠6, ∠10 should be the same as ∠3, ∠7 same as ∠5 and ∠9 same as ∠4
in the options we are only given '∠8 should be the same as ∠6' as the correct answer, so we take that.
3) from the image we can see that both horizontal lines are parallel to each other, so both angles on the lines should be same, so ∠CET would be (2x-16)°
(2x-16)°+(7x+20)°=180°
we get x=20(nearest whole number)
∠CED=7x+20=7(20)+20=160°
4) since we need to show that they are parallel,
(2x+30)°=(4x-90)°
2x-4x=-90-30
-2x=-120
x=60
we then plug the x value into the two equations, in which we get 150° for both the angles [2(60)+30=4(60)-90] ⇒ (150=150)
I hope u understand it the way I put it.

Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y=330(1.46)
Answer:
It is growth and the percentage increase is 46%
Step-by-step explanation:
The general form of an exponential function is;
Y = I(1 + r)^n
where Y is the present value, I is the initial, r is the growth or decay ratio, n is the number of times
To know if an exponential function is growth or decay, we need to know the repeating factor
If repeating factor is greater than 1, we have growth, if otherwise we have decay (less than 1).
As we can see in this case, we have r greater than 2, so what we have is growth
To get the percentage increase since it is growth, we equate;
1.46 = 1 + r
r = 1.46-1
r = 0.46 which is same as 46%

Step-by-step explanation:
2 1/4 = 1 2/7÷x
what is x?
Answer:
x=4/7
Step-by-step explanation:
Change mixed fractions to improper fractions
2 1/4 = 9/4
1 2/7 =9/7
Therefore, we have
9/4=9/7÷x
9/7÷x is 9/7×1/x=9/7x
Then, we have
9/4=9/7x
Cross multipy
9×7x=9×4
63x=36
Make x the subject of the formula, we have
x=36/63
x=4/7

A car dealer advertises a 7% markup over cost. What is the selling price of a car that cost the dealer $13,000?
Answer:
Step-by-step explanation:
The selling price can be shown to be 13000 + 7% * 13000
Selling price = 13000(1 + 7/100) = 13000 (1 + 0.07 ) = 13000 * 1.07
Selling price = 13910

20 teachers have a cup of tea at break time. 2/5 of these teachers are women. 3/4 of the teachers had sugar in their tea, 3/5 of which were male. How many male teachers didn't have sugar?
Answer:
3 male teachers didn't have sugar
Step-by-step explanation:
total number of male teachers = 3/5 x 20 = 12
3/4 of teachers have sugar, which is 15
3/5 of 15 = 9 (number of males who had sugar)
total number of males (12) minus number who had sugar (9) equals number of males who didn't have sugar (3)
