Answer:
?=4
Step-by-step explanation:
?*(3+2)=12+8
?(5)=20
20/5=4
?=4
4*(5)=20
20=20
Answer:
20
Step-by-step explanation:
Well first you want to find out what 12 plus 8 is and that is 20 so first you do the parenthesis which is 3+2 and that is 5 and 5x4 is 20 so your answer is 20

In a batch of 500 calculators, 25 were found to be defective. What is the probability that a calculator chosen at random will be defective? Write the probability as a percent.
Answer: 5%
Step-by-step explanation:
Probability for any event = [tex]\dfrac{\text{Number of favorable outcomes}}{\text{total outcomes}}[/tex]
Given: Number of defective calculators = 25
Total calculators = 500
The probability that a calculator chosen at random will be defective= [tex]\dfrac{25}{500}[/tex]
[tex]=0.05[/tex]
[tex]=0.05\times100\%\\\\= 5\%[/tex]
Hence, the required probability = 5%
What is the image of (5,0) after a dilation by a scale factor of 3 centered at the origin?
Given:
The point (5,0) dilated by a scale factor of 3 centered at the origin.
To find:
The coordinates of image.
Solution:
If a figure dilated by a scale factor of k centered at the origin, then the rule of transformation is
[tex](x,y)\to (kx,ky)[/tex]
The point is dilated by a scale factor of 3 centered at the origin, then the rule of transformation is
[tex](x,y)\to (3x,3y)[/tex]
The given point is (5,0). Putting x=5 and y=0, we get
[tex](5,0)\to (3(5),3(0))[/tex]
[tex](5,0)\to (15,0)[/tex]
Therefore, the image of (5,0) is (15,0).
Answer:The point (5,0) dilated by a scale factor of 3 centered at the origin.
To find:
The coordinates of image.
Solution:
If a figure dilated by a scale factor of k centered at the origin, then the rule of transformation is
The point is dilated by a scale factor of 3 centered at the origin, then the rule of transformation is
The given point is (5,0). Putting x=5 and y=0, we get
Therefore, the image of (5,0) is (15,0).

Answer:
22°
Step-by-step explanation:
m∠JKL = 5x -3
m∠KIJ = 2x +8
m∠IJK = x -1
m∠JKL = m∠KIJ +m∠IJK
5x-3 = 2x+8 +x-1
5x-2x-x = 8-1+3
2x = 10
x= 10/2=5
m∠JKL = 5x-3= 5*5-3=25-3=22°

Answer:
-l -2-18l=-l-20l=-20
Answer:
[tex]\boxed{-20}[/tex]

Step-by-step explanation:
Absotule value
[tex]|x| = x[/tex] if [tex]x \geq 0[/tex]
[tex]|x| = -x[/tex] if [tex]x < 0[/tex]
.
a = -2
b = 6

4 x (8 + 5) + 9 can someone help me out plz
Step-by-step explanation:
4x(8+5)+9
=52x+9
=52x+9
Description:
The first step is to simplify the equation provided. So in this case the equation is 4 x (8 + 5) + 9. After that you will get your answer as =52x+9. So in this case 4 x (8 + 5) + 9 = =52x+9.
Answer: =61
Hope this helps.
Answer:
4x8 +4x5 + 9=
32+20+9=61
Or we can do
4 x (13) + 9=
52+9=61

Step-by-step explanation:
[tex] {5}^{2x - 1} = {12}^{x} \\ \\ taking \: log \: on \: both \: sides \\ \\ log {5}^{2x - 1} = log {12}^{x} \\ \\ (2x - 1)log {5} = x \: log \: 12 \\ \\ 2x \: log \: 5 - log \: 5 = x \: log \: 12 \\ \\ x \: log \: 5 ^{2} -x \: log \: 12 = log \: 5 \\ \\ x \: (log \: 25 -log \: 12) = log \: 5 \\ \\ \\ x = \frac{log \: 5 }{(log \: 25 -log \: 12) } \\ \\ x = \frac{0.698970004}{1.39794001 -1.07918125 } \\ \\ x = \frac{0.698970004}{0.318758763 } \\ \\ x = 2.19278679 \\ \\ x \approx 2.19[/tex]

Use properties of operations to write two equivalent expressions for 13(4 + x).
1. Explain how to distribute the 13 to the terms inside the parentheses, then do the distribution. Use multiplication to simplify the result.
Write your answer in the space below.
2. Write another equivalent expression by using the commutative property of addition.
Write your answer in the space below.
Answer:
ok bet
Step-by-step explanation:
2 equal expressions for 13(4 + x):
52 + x
4(13 + x)
explanation: to distribute the 13 to the terms inside the parentheses, you simply multiply 13 by 4, and then 13 by x. this will then give you 52, and 13x.
2. another equal expression with commutative property of addition:
52 + x

A vendor sold a total of 413 large fries and souvenir sodas in one day. The total sales were $1068. Large fries cost $1.20 and souvenir sodas cost $3. Which system of linear equations can be used to find L, the number of large fries sold, and S, the number of souvenir sodas sold?
Answer:
[tex]L+S=413----------------1\\\\1.2L+3S=1068---------2[/tex]
Step-by-step explanation:
Step one:
given data
A vendor sold a total of 413 fries
Large fries cost $1.20 and souvenir sodas cost $3
let L be the number of large fries sold and S be the number of souvenir sodas
so
L+S=413
and
1.2L+3S=1068
Therefore the system of equation is
[tex]L+S=413----------------1\\\\1.2L+3S=1068---------2[/tex]

Answer:
x = -10
Step-by-step explanation:
We assume your equation is ...
[tex]\dfrac{1}{x}-\dfrac{1}{x-5}=\dfrac{1}{3x}[/tex]
Subtracting the right side, then expressing with a common denominator gives ...
[tex]\dfrac{3}{3x}-\dfrac{1}{3x}-\dfrac{1}{x-5}=0\\\\\dfrac{2}{3x}-\dfrac{1}{x-5}=0\\\\\dfrac{2(x-5)-3x}{3x(x-5)}=0\\\\\dfrac{-x-10}{3x(x-5)}=0\\\\\boxed{x=-10} \qquad\text{equate the numerator to 0 and add $x$}[/tex]
