Answer:

x=4/7

Step-by-step explanation:

Change mixed fractions to improper fractions

2 1/4 = 9/4

1 2/7 =9/7

Therefore, we have

9/4=9/7÷x

9/7÷x is 9/7×1/x=9/7x

Then, we have

9/4=9/7x

Cross multipy

9×7x=9×4

63x=36

Make x the subject of the formula, we have

x=36/63

x=4/7

Answer:

K = 2y + 4

Step-by-step explanation:

Let K = Keith

The expression that can be used to find Keith's age will be K = 2y + 4.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It given that, Keith is 4 years older than twice sheila's age. Sheila is y years old.

Suppose the age of Keith is shown by K and Sheila is y years old.

Expression is the combination of constants and variables with mathematical operators.

The expression can be used to find Keith's age is obtained as,

K = 2y + 4.

Thus, the expression that can be used to find Keith's age will be K = 2y + 4.

Answer: its C i got it right :)

Answer:

arc BC=96 degrees

angle B=55 degrees

angle C=77 degrees

arc AB=154 degrees

(check: 48+55+77=180 and 110+154+96=360)

Step-by-step explanation:

angles A, B, & C are inscribed angles

angle A=1/2 arc BC

arc BC=96

since arc AC=110, then arc AB=360-110-96

arc AB=154

angle B=1/2(110)

angle B=55

angle c=1/2(154)

angle c=77

Answer:

12

Step-by-step explanation:

10/5/6=10*6/5=12

12 is the answer, hope this helps!!

It should be 125 as

BC=100

and it's four times the length of AB then

100/4=25

then 100+25=125

Answer:

3/16 gallon

Step-by-step explanation:

From the given information in the question, we want to get the number of gallons of apple juice contained in the mixture

From the question, we are told this is 3/16 gallon

So the number of gallons of apple juice contained in the mixture is 3/16

Answer:

£84.5

Step-by-step explanation:

Given ratio = 2:5:6

Amount that Louis got from the total amount = £39

Step 1: Add the ratio together

2+5+6=13

Step 2: covert the given ratio into fraction

George ratio=2/13

Charlotte ratio=5/13

Louis ratio= 6/13

✓LET THE AMOUNT THAT WAS SHARED AMONG THEM= Y

But we know that Louis got £39, then we can compute How much did they shared using "Louiz" shrare as

Louis ratio= 6/13 × Y= £39

= 6Y/13 = 39

Cross multiply

13×39= 6Y

507= 6Y

Y= 84.5

Hence, the amount they shared was £84.5

Answer:50/100

Step-by-step explanation: 50/100 simplifies into 5/10, meaning they equal each other. 50 is half of 100, and 5 is half of 10.

Answer:

x=109

Step-by-step explanation:

The angles inside of a triangle all add up to 180 degrees. So:

Answer:

complet the squares

(x^2+14x)+(y^2+12y)=-60

add negative and positive 1/2 of linear coefs inside parenthaees

14/2=7, 7^2=49

12/2=6, 6^2=36

(x^2+14x+49-49)+(y^2+12x+36-36)=-60

factor perfect square

((x+7)^2-49)+((y+6)^2-36)=-60

get rid of parnthaeses

(x+7)^2-49+(y+6)^2-36=-60

(x+7)^2+(y+6)^2-85=-60

add 85 to both sides

(x+7)^2+(y+6)^2=25

The expression that represents Cindy's profit is $3.5b - $128.09.

Cindy's total profit is $30.82.

Profit is total revenue less total cost. Total revenue is the selling price per unit multiplied by the total units sold.

Profit = total revenue - total cost

($3.50b) - ($65.25 + $62.84)

$3.5b - $128.09

Profit for the first day = $3.5(24 + 15)  - $128.09

= ($3.5 x 39) - $128.09

= $136.50 - $128.09

=$8.41

Profit for the next day = $3.5(26 + 17)  - $128.09

= ($3.5 x 43) - $128.09

= $150.50 - $128.09

= $22.41

Total profit = $22.41 + $8.41 = $30.82
