First, write it as an equation
2.50+3x=5.05
Next, subtract 2.50 from both sides
2.50-2.50+3x=5.05-2.50
3x=2.55
Divide 3 on both sides
3x/3=2.55/3
x=0.85
The cost of a bag of chips is 0.85
hope i helped :D
Answer: 5cups of flour = 1 loaf of bread
45 loaves of bread multiplied by 5 cups of four = 225 cups of flour to make 45 loaves of bread.
225 cups of flour divided by 4 = 56.25 pounds of flour.
Answer:
Height = 14.4
Step-by-step explanation:
The diagonals meet at right angles. Interesting property.
The hypotenuse is the side of the rhombus = 15 cm
One of the sides of the small triangles created by the intersection of the diagonals = 24/2 = 12
You can find the other side of the the triangle by using the Pythagorean Theorem
a^2 + b^2 = c^2
c = 15
a = 12
b = ?
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 225 - 144
b^2 = 81
b = 9
The area of this right angle = 9 * 12/2 = 54
There are 4 of them so 4 * 54 = 216
That's the area of the rhombus.
The h= Area / b
b = 15
h = 216/15
h = 14.4
Answer:
x=2;DE,EF=9,DF=5
Step-by-step explanation:
Since DEF is isoceles, you can set the equations
x+7 and 2x+5 equal to each other
x+7=2x+5, now solve for x
-x=-2,
x=2, now plug in for each side
DE,EF=9
DF=3(2)-1=5
Assuming the frame is a perfect circle
and 3 inches wide indicates the diameter
area of a circle=pi times radius^2
diameter=2 times radius
radius=1/2 diameter
diameter=3
radius=1/2 times 3
radius=3/2=1.5
area=pi times 1.5^2=2.25
pi is aprox 3.14 so
2.25 times 3.14=7.065 square inches
the answer is 2.25π square inches or 7.065 square inches
