Answer: x=4 and y=3
Step-by-step explanation:
We start eliminating the same numbers with the same variable. So we take out 5y on both equation. We then subract 3x to 6x and we do the same to the right side. We end up having 3x=12 and then we divide 12/3=4. We plug 4 on the x values in one of the equation to find out the y value on that equation. You end up with y=3 and then plug that in the same equation on both to see if its right. Finally after that its correct.
Write down in terms of n, an expression for the nth term
of the following sequences:
a) 12 10 8 6 4
b) 25 20 15 10 5
Answer:
In bold below.
Step-by-step explanation:
a) 12 10 8 6 4
This is an arithmetic sequence with common difference -2.
nth term = a1 + (n - 1)d
= 12 + (n - 1)-2
= 12 -2n + 2
= -2n + 14.
b) 25 20 15 10 5
This is an arithmetic sequence with common difference -5.
nth term = a1 + (n - 1)d
= 25 + (n - 1)-5
= 25 - 5n + 5
= -5n + 30.

Help please!!! Find the measure of A in the picture below.
Answer:
Step-by-step explanation:
If you draw in BD, you can show that triangle BCD = triangle BAD by SSS
That means that <A = <C parts of congruent parts are congruent.
<A + <C + 115 + 71 = 360
<A + <C + 186 = 360 All convex quadrilaterals have 4 interior angles that add to 360 degrees
<A + <C = 360 - 186
<A + <C = 174
So call <A and < C = x
x + x = 174
2x = 174
x = 174 / 2
x = 87
<A = 87
Which choice is equivalent to the quotient below?
40/8
Answer:
A.
Step-by-step explanation:
You simplify the square root until you narrow it down to the square root of 5.
The quotient of expression of √40/√8 is √5 which is correct option (A).
What is expression?Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation : Divides left hand operand by right hand operand
For example 4/2 = 2
Given expression as :
⇒ √40/√8
Factor of √40 = √8×√5
⇒ (√8√5)/√8
Cancel out of√8
⇒ √5
Hence, the quotient of expression of √40/√8 is √5.

Answer:
DF ≅ AC
Step-by-step explanation:
To prove that the triangles are congruent by AAS, we need a side from each triangle to be congruent to the other, correspondingly. So, if AC ≅ DF, we could prove the triangle's congruency by AAS. In the answer choices, the only answer that works is DF ≅ AC.

One year, the population of a city was 132,000. Several years later it was 149,160.
Find the percent increase.
Answer: 13%
Step-by-step explanation:
To find the percent increase, first find the increase in figures:
= 149,160 - 132,000
= 17,160 people
Then find the percent increase in this manner:
= Increase / Previous population * 100%
= 17,160 / 132,000 * 100%
= 13%
