Answer:
The answer is: amount of flour used for bread and brownies is same
Step-by-step explanation:
Step 1:
Assume;
Flour used for cookies = x
Flour used for bread = z
Flour used for brownies = y
Flour used for cookies = a
Step 2:
Now, for bread as mentioned flour used for bread is one fourth less than flour used in cookies therefore;
z = x - (1/4)x
z = x-0.25x
z = 0.75x
Step 3:
Now, for cookies as mentioned flour used for cookies is one third more than flour used in brownies therefore;
x = (1/3)y + y
x = 0.33y + y
x = 1.33y
Step 5:
Value of z from step 2:
z = 0.75x
now put value of x from step 3 in above equation;
z= 0.75 (1.33y)
z = (1) y
hence proved;
z = y
Answer:
C) $10
Step-by-step explanation:
What the graph is showing is that she makes $20 for every 2 masks she sells so just divide 20 by 2 which is 10 and that’s how much she is selling for one mask.
The inequality can be used to determine how many months will it take for Caroline's hair to be at least as long as Trinity's hair is (1/5)x + 7 ≥ (1/10)x + 10
<h3>What is an
equation? </h3>
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Let x represent the number of months.
For Caroline's hair:
Length = (1/5)x + 7
For Trinity's hair:
Length = (1/10)x + 10
For Caroline's hair to be at least as long as Trinity's hair, hence:
(1/5)x + 7 ≥ (1/10)x + 10
The inequality can be used to determine how many months will it take for Caroline's hair to be at least as long as Trinity's hair is (1/5)x + 7 ≥ (1/10)x + 10

(x+2)(2x-5)=56
2x^2-5x+4x-10=56
2x^2-x-10=56
2x^2-x-66=0
2x^2-12x+11x-66=0
2x(x-6)+11(x-6)=0
(2x+11)(x-6)=0, since x is a measurement x>0 so:
x=6cm
