Is 40 divided by the square root of 4 a rational number?

Answer:

x = 1, y = 1

Step-by-step explanation:

plug y = 2x - 1 into the equation x + y = 2:

[tex]x + (2x - 1) = 2\\3x - 1 = 2\\3x = 3\\x = 1[/tex]

plug that into the equation y = 2x - 1

[tex]y = 2*1-1\\y=2-1\\y=1[/tex]

Step-by-step explanation:

Carter's speed is 60, and Vitor's speed is 100. To find how much slower, Carter was, subtract Vitor's speed from Carters. 40 is the difference.

Answer:

Carter is about 17% slower than vitor

Step-by-step explanation:

Carter is 14/60 = 23.33/100

Vitor is 40/100

Answer:

26.3 grams

Step-by-step explanation:

57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)

f(-5) = -50 - 20

f(-5) = -70

Answer:

f(-5) = -70

Step-by-step explanation:

f(-5) = 10(-5)-20

since she paid $5 admission subtract it from $7.25

Answer:

Four boys and one girl.

Step-by-step explanation:

Total students wearing glasses = 5

Separate the students by x and x + 3. It is x + 3 for the boys because there are three more boys wearing glasses.

Girls = x

Boys = x + 3

Total = 5

Calculate:

x + x + 3 =5

2x + 3 =5

2x = 2

x = 1

Boys wearing glasses = (1) + 3 = 4

Girls wearing glasses = 1

Answer:

(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])

Step-by-step explanation:

4x + 9y = 24

x + y = 10 $\Rightarrow$ x = 10 - y

Substituting the value of x (second equation) into the first equation, we get:

4 * (10 - y) + 9y = 24

40 - 4y + 9y = 24

5y = -16

y = -16/5.

So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]

Answer:

16.08

Step-by-step explanation:

IF Alberts bank account decreased by a total of 193 over a period of 12 days, then;

193 = 12days

To determine the average daily decrease in his account, thwn;

x = 1 day

Divide both equations

193/x = 12/1

12x = 193

x = 193/12

x = 16.08

Hence the average daily decrease in his account is 16.08

Answer:

5/7 x 3/4 = find the common denominator.

Then,

Let’s say 28.(multiply seven to the second fraction and 4 to the first.)

So,

20/28x21/28.

Then, cross multiply the numerator of the first fraction by the denominator of the second. Same for the denominator of the first and numerator of the second.
