explain why 13x +1 = 11x+9
Answer:
x=4
Step-by-step explanation:
13x+1 = 11x+9
13x-11x = 9-1
2x = 8
x = 4
Answer:
53 = 53
Step-by-step explanation:
13x+1=11x+9 13(4)+1=11(4)+9
13x=11x+8 52+1=44+9
2x=8 53=53
x=4

Kelly was baking bread but could only find her ⅛ cup measuring cup. She needs ¼ cup sugar, ¾ cup whole wheat flour, and ½ cup all-purpose flour. How many ⅛ cups will she need for each ingredient?
Answer:
Number of 1/8 cups of sugar needed = 2
Number of 1/8 cups of whole wheat flour needed = 6
Number of 1/8 cups of all purpose flour needed = 4
Step-by-step explanation:
Recipes Kelly needs:
Sugar = 1/4 cups
Whole wheat flour = 3/4 cups
All purpose flour = 1/2 cups
She could only find her ⅛ cup measuring cup.
How many ⅛ cups will she need for each ingredient?
Number of 1/8 cups of sugar needed = cups of Sugar needed / 1/8 cups
= 1/4 ÷ 1/8
= 1/4 × 8/1
= 8/4
= 2
Number of 1/8 cups of sugar needed = 2
Number of 1/8 cups of whole wheat flour needed = cups of whole wheat flour needed / 1/8 cups
= 3/4 ÷ 1/8
= 3/4 × 8/1
= 24/4
= 6
Number of 1/8 cups of whole wheat flour needed = 6
Number of 1/8 cups of all purpose flour needed = cups of all purpose flour needed ÷ 1/8 cups
= 1/2 ÷ 1/8
= 1/2 × 8/1
= 8/2
= 4
Number of 1/8 cups of all purpose flour needed = 4

HELP ME
PLEASE IM DESPERATE
V = [?]cm3
6cm
Answer:
Half of 6 is 3(new radius)
3^3 = 9
9 x 3.14 = 28.26(area of circle)
Now we multiply by height
28.26 x 5 = 141.3
Now we divide by 3 since its part for the formula of finding the cone's volume:
141.3 x 1/3(basically just dividing by 3) = 47.1
Now let's find the volume of the cylinder:
3^3 = 9, 9 x 3.14 = 28.26
28.26 x 14 = 395.64
Now let's add the given volumes:
395.64 + 47.1 = 442.74 cm^3 is your answer.

Answer:
the arc length is 555.17 cm
Step-by-step explanation:
The equation to solve for the arc length is: s = rΘ, where r represents the radios and the Θ represents radians. In order to solve this you need to convert degrees into radians with the formula: radians = degrees ·
You want to find the distance the golf club travels when the golfer swings the club.
First you need to subtract 25° from 360°
360° - 25° = 335°
now you need to convert 335° into radians
radians = degrees ·
radians = 335° · you multiply 335° by
radians = 335/180 then you simplify
radians = 67/36
335° = 67[tex]\pi[/tex]/36
Now we plug everything we know into the equation s = rΘ
s = rΘ
s = 95 (67[tex]\pi[/tex]/36) first multiply 67 by 3.14
s = 95 (210.38/36) divide 210.38 by 36
s = 95 (5.843888889) and multiply 95 by 5.843888889
s = 555.1694444 *remember to simplify to the nearest hundredth
s = 555.17 cm
hope this helps! if u have any questions, let me know!
Solve 5x/3 + 2/5 = 1
x = 9/25
x= 25/9
x= 3/25
x = 9/27
Answer:
[tex]x=\frac{9}{25}[/tex]
x = 0.36
Step-by-step explanation:
5x/3 + 2/5 = 1
5x/3 + 2/5 - 2/5 = 1 - 2/5
[tex]\frac{5x}{3} = 0.6[/tex]
5x/3 × 3 = 0.6 × 3
5x = 1.8
5x ÷ 5 = 1.8 ÷ 5
[tex]x=\frac{9}{25}[/tex]
x = 0.36

Measure of the other base angle: 52°
Measure of the third angle: x
Sum of the measures of the three angles: 180°
Equation:
x + 52 + 52 = 180
x + 104 = 180

The radius of a circle is 2 meters. What is the circle's area?
(use 3.14 for π)
Answer:
it is approximately 12.57meters
Answer:
12.56 meters
Step-by-step explanation:
The area of a circle is πr², where r is the radius of the circle.
First we square the radius, which is 2. 2²=4.
Now our area is 4π.
Using 3.14 for π, we can say the area is 4 × 3.14, which is equal to 12.56
Stella invested $6100 in an account paying interest rate of 6 1/2 % compounded monthly. Katherine invested $6100 in an account paying an interest rate of 6 5/8 % compounded quarterly. After 7 years how much more money would Katherine have in here account than Stella, to the nearest dollar
Answer:
Katherine would have $109.54 more than Stella.
Step-by-step explanation:
Giving the following information:
Stella:
Initial investment (PV)= $6,100
Interest rate (i)= 0.065/12= 0.0054 per month
Number of periods (n)= 7*12= 84
Katherine:
Initial investment (PV)= $6,100
Interest rate (i)= 0.06625/4= 0.0167
Number of periods (n)= 7*4= 28
To calculate the future value, we need to use the following formula:
FV= PV*(1 + i)^n
Stella:
FV= 6,100*(1.0054^84)
FV= $9,589.5
Katherine:
FV= 6,100*(1.0167^28)
FV= $9,699.04
Difference= $109.54
Katherine would have $109.54 more than Stella.

find two numbers if their sum is 3/5 and their difference is 7 1/5
Answer:
A = 3 + 9/10
B = -(3 + 3/10)
Step-by-step explanation:
We have two numbers, A and B, such that:
A + B = 3/5
A - B = 7 + 1/5
To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:
A = 3/5 - B
Now we can replace this in the other equation:
A - B = 7 + 1/5
(3/5 - B) - B = 7 + 1/5
3/5 - 2*B = 7 + 1/5
-2*B = 7 + 1/5 - 3/5
-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5
B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)
Now that we know the value of B, we can use the equation
A = 3/5 - B
To find the value of A:
A = 3/5 - ( -(3 + 3/10))
A = 3/5 + (3 + 3/10) = 6/10 + 3 + 3/10 = 3 + 9/10
The numbers are:
A = 3 + 9/10
B = -(3 + 3/10)
