Ryan's rate of change is ________ Taylor's rate of change .
Ryan'sstaring balanced is_______ Taylor's starting balanced.
We want to compare the rates of change and starting balances of Ryan and Taylor, the correct answers are:
"Ryan's rate of change is _less than_ Taylor's rate of change.""Ryan's starting balance is greater than Taylor's starting balance."So we know that Ryan's savings plan can be modeled by:
S(m) = 15*m + 50.
This means that he starts with 50, and saves 15 per month, then:
Ryan's rate of change = 15 per monthRyan's initial balance = 50For Taylor we have a table:
month amount saved:
0 25
1 45
2 65
3 85
So, in month 0 he has 25, thus, his initial balance is 25.
And each month the amount saved increases by 20, then the equation is:
T(m) = 20*m + 25
Then we have:
Taylor's rate of change = 20 per month.Taylor's initial balance = 25Now we can see that:
"Ryan's rate of change is _less than_ Taylor's rate of change."
"Ryan's starting balance is greater than Taylor's starting balanced."

Carlos: 2(14x - 4)
Danny: 7(4x - 1)
Irene: 4(7x - 2)
Which student(s) offered answer(s) equivalent to the original expression?
Equivalent expression for the given expression is
4(7x-2)
Irene offered answer equivalent to the original expression
Given :
Mrs. Crosland asked students to factor the expression 28x - 8
The student are given some expression . To find correct expression , we need to factor the given expression
[tex]28x-8[/tex]
Both 28 and 8 are divisible by 4
Lets factor out 4 from the given expression.
When we factor out 4, then we divide each term by 4
[tex]28x-8\\4(\frac{28}{4} -\frac{8}{4} )\\4(7x-2)[/tex]
The students offered the answers shown
Carlos: 2(14x - 4)

Answer:
J 3/4 cup
Step-by-step explanation:
Step 1: read and understand the question.
The question is giving you amounts of flour and 2 types of sugar.
The question is asking for a difference between two quantities:
the amount of flour (2 1/4 cups)the combined amount of sugar (3/4 cup white, 3/4 cup brown)Step 2: determine the relations you need to use to solve the problem
You need the combined amount of sugar, which you find by adding the quantities of each of the kinds.
3/4 cup white + 3/4 cup brown = 6/4 cup sugar combined
You need the difference of that quantity from the quantity of flour, which you find by performing subtraction:
flour - sugar = (2 1/4) - (6/4) . . . . cups
Step 3: Use your knowledge of arithmetic.
(2 1/4) -(6/4) = 9/4 -6/4 = (9 -6)/4 = 3/4
Step 4: Answer the question that was asked.
The difference between the flour and sugar amounts is 3/4 cup.

If cost of 15 eggs is ? 75, then find out the cost of 4 dozens eggs.
Answer:
Each egg is $5 so 4 dozen(48) is $240
Step-by-step explanation:
the way to do this is 75/15= 5
and then you multiply 12 x 4 to get 48 eggs
and then multiply 48 x 5 to get $240
15:75
divide each by 5
3:15
(4 dozen is 48 -> 48/3 = 16)
multiply each by 16
48: 240

I actually did not get 6 for an answer
4x+a=4x+3
cancel equal terms on both sides of the equation
a=3
which means the x would be all reals cause it is true.

Answer:
∠ABC = 54°
Step-by-step explanation:
an inscribed angle is 1/2 the size of an incenter angle.
so:
∠AMC = 2(∠ABC)
10x - 12 = 2(4x + 6)
10x - 12 = 8x + 12
simplify:
2x = 24
x = 12
∠ABC = 4(12) + 6 = 54°
