Answer:

I believe it's 42

Step-by-step explanation:

Replace each letter in the expression with the assigned value.

First, replace each letter in the expression with the value that has been assigned to it. To make your calculations clear and avoid mistakes, always enclose the numbers you're substituting inside parentheses. The value that's given to a variable stays the same throughout the entire problem, even if the letter occurs more than once in the expression.

However, since variables "vary", the value assigned to a particular variable can change from problem to problem, just not within a single problem.

Perform the operations in the expression using the correct order of operations.

Once you've substituted the value for the letter, do the operations to find the value of the expression.

Brian deposits $7000 into an account that pays simple interest at an annual rate of 3%. He does not make any more deposits. He m

Andre45 [30]

Answer:

A)1050

B)8050

Step-by-step explanation:

to find interest we use the formula A= P(1+rt) where P is the initial investment, r is the rate percent, and t is the time interval

for this question we have A=7000(1+3(5)) which gives 8,050 dollars which is the answer to part B

for part A we simply subtract the answer from B from the initial investment so 8050 - 7000 = 1050 made from interest

What is the quotient of 5 7 ÷ 5 14 ?

KatRina [158]

Answer:

<h2><u>=</u> <u> 57 / 514 </u> <u>(Decimal: 0.110895)</u></h2>

Step-by-step explanation:

57 / 514

<u>(Decimal: 0.110895)</u>

<u></u>

<h2><u>And if that is not what you are looking for here: </u></h2><h2><u></u></h2>

Rewrite the equation as

x /14 = 5/ 7 . x/ 14 = 5/ 7

Multiply both sides of the equation by

14.14 ⋅ x /14 = 14 ⋅ 5 /7

Simplify both sides of the equation.

Tap for fewer steps...

Cancel the common factor of 14 .

Cancel the common factor.

14 ⋅ x /14 = 14 ⋅ 5 /7

Rewrite the expression.

x = 14 ⋅ 5 /7

Simplify 14 ⋅ 5/ 7 .

Cancel the common factor of 7 .

Factor 7 out of 14 .

x = 7 ( 2 ) ⋅ 5/ 7

Cancel the common factor.

x = 7 ⋅ 2 ⋅ 5/ 7

Rewrite the expression.

x = 2 ⋅ 5

Multiply 2 by 5 .

Pls helppp me with this

Annette [7]

Answer:

Step-by-step explanation:

Applying,

The angle bisector theorem of triangle

From the diagram,

Since ΔAMT is an issoceless triangle,

Then,

Line OA divides Line MT into two equal parts.

Therefore,

Line MO = Line OT.............. Equation 1

From the diagram,

Line MO = 4x-1, Line OT = 3x+3

Substitute into equation 1

4x-1 = 3x+3

Collect like terms

4x-3x = 3+1

x = 4.

Therefore,

OT = 3(4)+3

OT = 12+3

OT = 15

How do I use the substitution method to find the point of intersection of

Goshia [24]

To substitute, solve for one variable and then plug it into the other equation you have. In this problem, y is already solved for on the top equation (y=x+2), so you just stuff it into the second equation.

y = x + 2
3y = 4x - 2

3(x + 2) = 4x - 2
3x + 6 = 4x - 2
-x = -8
x = 8
y = x + 2 = 8 + 2 = 10

solution:
x = 8
y = 10

hope this helps!! :)
