Step-by-step explanation:
$52.45
49.95×.05
then add that result to 49.95= answer
Answer:
1010
Step-by-step explanation:
There are a whole class of questions that rely on the method to this one.
First add up what you know
1270 + 1150 + 870 + 1450 = 4740
Now add on the 5th month (which you don't know. Call it x)
4740 + x
Divide by 5
(4740 + x)/5 = 1150 and that is your equation
Solution
Multiply both sides by 5
5*(4740 + x) / 5 = 1150 * 5
4740 + x = 5750
Subtract 4740 from both sides
4740 - 4740 + x = 5750 - 4740
x = 1010
Which seems kind of low, but that's what the numbers come to.
Answer:
XXL = $19.75
Box of Breadstick = $3.5
Step-by-step explanation:
Given that:
Let :
cost per XXL pizza = x
Cost per box of bread stick = y
4x + 2y = 86 - - - (1)
6x + 4y = 132.50 - - - (2)
From (1): Divide (1) by (2)
2x + y = 43 - - - (3)
y = 43 - 2x
Substitute y = 43 - 2x into (2)
6x + 4(43 - 2x) = 132.50
6x + 172 - 8x = 132.50
-2x + 172 = 132.50
-2x = 132.50 - 172
-2x = - 39.50
x = $19.75
y = 43 - 2x
y = 43 - 2(19.75)
y = $3.5
Y=90° by inspection
w=180-(50+y)=160-(50+90)=40°
x=180-(w+x)=180-(40+97)=43°
z=180-(x+90)=180-(43+90)=47°
The area of a rectangle is length*width
Since we have the width, we can do 5346/66 to get the length
So the length is 81 cm
Hope this helped
