-10 if he paid his friend he still owes him 10 bucks still
First divide 93 by 3 to get 25% of the original price: 31. Then multiply it by 4 to get the whole original price, which is $124. Now onto the shoes.
Divide 119 by 17 to get 7, which is 5% of the original price for the shoes. Then multiply 7 by 20, which is $140 for shoes.
Subtract 124-93 to get 31, the savings on the dress and also subtract
140-119 to get 21, savings on the shoes. Then add them together to get a grand savings total of $52 in savings. Hope this helps!
Answer:
x= 8/5 - 4/5y
Step-by-step explanation:
To get x independent we need to get everything else on the side x is on to the other side. We can start by adding 4y to the other side. We add because its negative and negative and positive cancel each other out.
-5x-4y=-8
add 4y
-5x= - 8 + 4y
Then to get the negative 5 to the other side we divide it to cancel it because it is multiplying right now.
-5x= - 8 + 4y
divide -5
x= - 8/-5 +4/-5y
in the fraction -8/-5 the negatives cancel out to get 8/5 and for 4/-5y we can more the negative to get us our final answer which is x=8/5-4/5y
<u>Given:</u>
A larger circle consisting of two circles with radii of 4 cm and 8 cm each.
<u>To find:</u>
The area of the shaded region.
<u>Solution:</u>
The centers of the circles with radii 4 cm and 8 cm lie on the same line as the center of the larger circle.
So the diameter of the outer circle cm.
If the diameter is 24 cm, the radius is cm.
The area of the shaded region is obtained by subtracting the areas of the two inner circles from the outer circle.
The area of a circle
The area of the circle with radius 12 cm square cm.
The area of the circle with radius 8 cm square cm.
The area of the circle with radius 4 cm square cm.
The area of the shaded region square cm.
Rounding this off to the nearest tenth, we get the area of the shaded region as 201 square cm.
Notice that the plane figures above are congruent with each other, so that
<h3>#6</h3>
x/8 = 4/16
16x = 8 × 4
16x = 32
x = 2
<h3>#7</h3>
x/5 = 48/6
6x = 5 × 48
6x = 240
x = 40
<h3>#8</h3>
x/7 = 90/10
10x = 7 × 90
10x = 630
x = 63
<h3>#9</h3>
3/x = 10/40
10x = 3 × 40
10x = 120
x = 12
