Answer:
see explanation
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
A(1, 4 ) → A'(1, - 4 )
B(3, - 2 ) → B'(3, 2 )
C(4, 2 ) → C'(4, - 2 )
product= multiplication.
"double" means 
28 should be your answer!
Answer:
or 2.75, depending on what you need.
Step-by-step explanation:
- Subtract $269 by the service fee ($60). This will be $209.
- Divide $209 by $76 to calculate hours. This will be 2.75.
- (optional) We know that 0.75 is
, so let's take 2.75 and convert it into . This is your answer.
Sarah sold 66 posters
<em><u>Solution:</u></em>
Let "a" be the number of shirts sold
Let "b" be the number of posters sold
<em><u>Sarah sold a total of 178 t shirts and posters at a festival</u></em>
Therefore,
number of shirts sold + number of posters sold = 178
a + b = 178 ----------- eqn 1
<em><u>She sold 46 more tshirts than poster</u></em>
Number of shirts sold = 46 + number of posters sold
a = 46 + b --------- eqn 2
<em><u>Substitute eqn 2 in eqn 1</u></em>
46 + b + b = 178
2b = 178 - 46
2b = 132
b = 66
Thus she sold 66 posters
Solution:
Given ratio - 3:5
1 part = 3
2 part = 5
Total no. of parts = 3 + 5 = 8 parts
400 / 8 = 50
3 * 50 = 150
5 * 50 = 250
I think that's it :D
