A corner store sells two kinds of baked goods: cakes and pies. A cake costs $15 and a pie costs $13. In one
day, the store sold 9 baked goods for a total of $121. How many cakes did they sell?
a. 8 cakes
c. 7 cakes
b. 2 cakes
d. 4 cakes
Answer:
a. 8
Step-by-step explanation: Out of 12 baked goods sold , let the number of cakes sold, be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs, $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8

which fraction represents 35%
Answer:
7/20
Step-by-step explanation:
Answer:7/10
Step-by-step explanation:
Here is the way that I think is the simplest method of changing a percentage a fraction. This percentage has two digits in it, so put it over a 1 and two zeros and then simplify. 35/100 is simplified to 7/20.

Step-by-step explanation:
An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. 3/4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? (no decimals)
Answer:Weight of wood part of the sculpture (no decimals) =4kg
Step-by-step explanation:
Weight of sculpture containing metal and wood = 14.9 kg
weight of metal =3/4 x 14.9 kg =11.175kg
weight of wood =Entire sculpture − weight of metal
= 14.9 kg−11.175kg
=3.725kg
Rounding up to remove decimals we have that Weight of wood part =4kg

Find the area of the shaded region. Round your answer to the nearest tenth if needed.
Answer:
140 inches
Step-by-step explanation:
Find the area of the square.
4 + 10 = 14 (Length)
11 + 4 = 15 (Breadth/Width)
Area = 14 x 15 = 210 inches
Find the area of the 2 unshaded squares in the square.
Area of square at the top = 4 x 4 = 16 inches
Area of square at the bottom = 6 x 9 = 54 inches
Add the 2 squares of the area together.
16 + 54 = 70 inches
Now deduct the area of the huge box by the area of the 2 unshaded squares.
210 - 70 = 140 inches

I THINK I GOT IT OMG THAT WAS SO HARD
Answer:
z = 5
Step-by-step explanation:
[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]
It can be also written as -
[tex]\frac{2^2 \times x^2 \times y^7}{2^3 \times x^3 \times y^2} = \frac{1 \times x^0 \times y^z}{2 \times x^1 \times y^0}[/tex]
Using law of exponents , lets solve this.
[tex]=> 2^{(2-3)} \times x^{(2-3)} \times y^{(7 - 2)} = \frac{1}{2} \times x^{(0-1)} \times y^{(z-0)}[/tex]
[tex]=> 2^{-1} \times x^{-1} \times y^{5} = 2^{-1} \times x^{-1} \times y^z[/tex]
[tex]=> \frac{y^5}{2x} = \frac{y^z}{2x}[/tex]
[tex]=> y^z = y^5[/tex]
[tex]=> z = 5[/tex]
14. A system of equations is shown below. For what value of a will this system have no solutions? Justify your answer.
y = 4x-9
y = ax+6
Answer:
a = 4
Step-by-step explanation:
a = 4
If a = 4, then both lines have the same slope and different y-intercepts. That makes both lines parallel. Since the lines never intersect, there is no solution.
Answer:
x can not equal zero, as it would cause division by zero.
Step-by-step explanation:
First, let's make one equation out of them and see what we get. Because both of them have y on the left, we can say that the two right sides are equal, giving us:
4x - 9 = ax + 6
If we solve for a, we get:
ax + 6 = 4x - 9
ax = 4x - 15
a = 4 - 15 / x
With that arrangement we can see clearly that x can not be equal to zero, as it would give us division by zero.
Enter a number in each box so that the expressions are equivalent. (A) 0.8 (2x + x) + 3(7 - 4.1x) = x + 21 (B) 12 1 2 (6x + 22y) = x + y (C) (3x - ) - (6x + 1) = -3x - 2 (D) 112 1 2 x + 27y = (12 1 2 x + 9y)
The questions aren't well formatted ; from the values that are observable,
Answer:
Coefficient of x = -9.9 ;
Coefficient of x = 75
Coefficient of y = 275
Step-by-step explanation:
Given :
0.8 (2x + x) + 3(7 - 4.1x) = __x + 21
0.8(3x) + 21 - 12.3x = __x + 21
2.4x + 21 - 12.3x = __x + 21
-9.9x + 21 = __x + 21
-9.9
12 1/2 (6x + 22y) = x + y
75x + 275y = x + y
Answer:
The answers are:
1. -9.9x
2. 3x + 11y
3. 1
4. 3
