In Triangle WXY, angle X is equal to angle Y, WX is equal to 9x-11, XY is equal 4 points
to 4x+1, and WY is equal to 7x-3, find x and the measure of each side
Answers
Answer:
x = 4WX = WY = 25XY = 17Step-by-step explanation:
The triangle is isosceles with side WX equal to side WY:
WX = WY
9x -11 = 7x -3
2x = 8 . . . . . add 11-7x
x = 4
Then the side measures are ...
WX = WY = 7(4) -3 = 28 -3 = 25
XY = 4(4) +1 = 16 +1 = 17

levi finds a skateboard that sells 139.99. the store charges 6% sales tax about how much money will he have to spend for his skateboard?
Answers
The amount Levi spends on this skateboard is $148.39.
Tax is an amount levied on goods and services by the government. Taxes increases the price of goods and services.
The amount Levi spends on this skateboard = value of the tax + cost of the skateboard
value of the tax = 6% x $139.99
0,06 x $139.99 = $8.40
The amount Levi spends on this skateboard = $8.40 + $139.99 = $148.39

Which of the following is the estimated product of 45 and 50? no links please
Answers
Answer:
3500
Step-by-step explanation:
Hello, you need to eliminate fractions in numbers in such questions. So you have to round. If we round the number 45, we get 50. We don't need to round 50 because 50 has no fractions.
1 - 45 - - > 50
2- 50 - - > no change
3- 50 × 50 = 50² = 3500

Answer:
y= 27-6x
Step-by-step explanation:
For the first equation you add 6x on both sides which will leave us at
-y=-27+6x. You then divide both sides by a -1 to make the y positive so then it'll give us the equation y= 27-6x . For the second equation subtract 18x on both sides which will leave us with the equation 3y= 81-18x . Divide each side by 3 to get the y by itself. Then the equation will be y=27-6x

The answer is 3/2 x 63
Step-by-step explanation:
3/2*63 = 189 / 2 = 94.5
7/8*63 = 441 / 8 = 55.125
2/3*63 = 126 / 3 = 42
4/5*63 = 252 / 5 = 50.4
Therefore the answer is 3/2 x 63 because it’s product is greater than 63.

Choose the two expressions that are equivalent to 6.5 ÷ 1.3.
A 65 ÷ 13
B 65 ÷ 130
C 650 ÷ 130
D 650 ÷ 13
Answers
Answer:
A & C
Step-by-step explanation:
To find the two expressions that are equivalent to 6.5 ÷ 1.3, you need to solve all of them until you get the two expressions that have a quotient of 5.
Let's begin solving!
65 ÷ 13 = 5
So now we know that A is one of our answers
65 ÷ 130 = 0.5
Not one of our answers because the quotient is not 5
650 ÷ 130 = 5
This is our other answer! We don't need to solve D because we only needed to find two expressions which are A and C.
Hope this helps you :)
Answers are A and C.
6.5 ÷1.3 = 5
A. 65 ÷ 13 = 5 so yes
B. 65 ÷ 130 = .5 so no
C. 650 ÷ 130 = 5 so yes
D. 650 ÷ 13 = 50 so no

3x-9y=-7 ; 2y-6x=8 elimination
Answers
Answer:
x=-29/24
y=3/8
Step-by-step explanation:
3x-9y= -7 ---A
2y-6x= 8----B
multiply eq A by 2
6x-18y=-14
-6x+2y=8
Add both equations, so you eliminate x since 6x+(-6x) = 0
-18y+2y= -16y
-14+8=-6
so you have
-16y=-6
y=3/8
now substitute this back to eq B, (you can use eq A as well if you like)
2(3/8)-6x=8
3/4-6x=8
-6x=29/4
x=-29/24

The ratio of two numbers is 4:9. When 5 is subtracted from each of them ,the now 38. Find the numbers
Answers
Given : The ratio of two numbers is 4:9. When 5 is subtracted from each of them the ratio is 3:8. Find the numbers
Need to Find : The numbers
Solution : According to the question here we are given that the ratio is 4:9 and 5 is subtracted from each of these ratios after which the ratio becomes 3:8. Let's follow the steps to get the answer.
Let the constant multiple be x
Now, according to the question:
The numbers are 4x and 9x
As we get to know that each of them is subtracted by 5. So,
1st number = 4x - 5
2nd number = 9x - 5
New ratio becomes 3:8
⇢ (4x - 5)/(9x - 5) = 3/8
⇢ 8(4x - 5) = 3(9x - 5)
⇢ 32x - 40 = 27x - 15
⇢ 32x - 27x = - 15 + 40
⇢ 5x = 25
⇢ x = 25/5
⇢ x = 5
Now, getting the numbers. Instead of x we need to put 5 and multiply with the constant.
1st number = 4x = 4(5) = 20
2nd number = 9x = 9(5) = 45
∴ The numbers are 20 and 45 respectively.

Rewrite the expression (4x² + 5x) ²-5(4x ² + 5x) – 6 as a product of four linear factors.
Answers
Answer:
(x+2)(x+1)(4x+1)(4x-3)
Step-by-step explanation:
(4x² + 5x)² - 5(4x² +5x) - 6
= (4x² + 5x)² - 6(4x² +5x) + 1(4x² +5x) -6
= (4x² + 5x)(4x² +5x -6) +1 (4x² +5x -6)
= (4x²+5x-6)(4x²+5x+1)
= (4x² + 8x - 3x - 6)(4x² + 4x + x +1)
= (4x(x + 2) - 3(x + 2))(4x(x+1) +1(x+1))
= (x+2)(4x-3)(x+1)(4x+1)
