1/5 of an even number is added to 2/3 of the next even number to obtain 88, find the even number word problem

Answers

Answer:

Step-by-step explanation:

Answer:

100

102

Step-by-step explanation:

Let the first even number be 2x

Let the next even number be 2x + 21/5 *(2x) + 2/3 (2x + 2) = 882/5 *x + 4/3 (x) + 4/3 = 88

Multiply by 15 to get rid of the fractions.2*3 x + 20x + 20 = 88 * 156 x + 20x + 20 = 1320 26x + 20 = 132026x = 1300x = 1300/26x = 502x = 1002x + 2 = 1021/5 * 100 = 202/3 * 102 = 34*2 = 6820 + 68 = 88

33- (8t) = 15

Answers

33 - 8t = 15
-8t = 15 - 33
-8t = -18
t = -18 / -8
t = 2.25

33-8t=15
33-15=8t
18=8t
18/8=t
t=2.25

What is the sum of the square root of 100 and the square root of 400

Answers

Answer:

Step-by-step explanation:

Square root of a number k will turn it into a number n such that n * n = k.

The square root of 100 is 10 because 10 * 10 = 100, and the square root of 400 because 20 * 20 = 400.

Now, we just need to sum 10 and 20: 10 + 20 = 30.

Thus, the answer is 30.

Hope this helps!

What is the equation of the linear function represented by the table? x y –5 14 –2 11 1 8 4 5 y = negative x + 9 y = negative x + 13 y = x + 13 y = x + 9

Answers

The equation that satisfies all the points is y= -x+9 and the correct option is A.

What is an Equation?

An equation is a statement that is formed when two algebraic expressions are equated using an equal sign.

The table of x-y represents a line

x y

5 14

-2 11

1 8

4 5

The equation that satisfies these values has to be determined.

Substituting (5,14)

The first equation is

y = -x+9

Substituting the values in the equation

14 = 5 +9

14=14

Substituting (-2,11)

11 = 2+9

11 = 11

Substituting (1,8) ; (4,5)

8 = -1+9

8 = 8

4 = -5+9

4=4

Therefore, The equation that satisfies all the points is y= -x+9, and the correct option is A.

Answer:

Answer:

1. y= -x+9

Step-by-step explanation:

plug the coordinates inside each of the equation

14 = -(-5)+9 --> 14 = 14

11 = -(-2)+9 --> 11=11

8 = -(1)+9 --> 8=8

5 = -(4)+9 --> 5=5
