To answer the question above, simplify both sides of the equation. This gives,
8x - 3 = 8x + 14
Next, cancel the term 8x because it appears on both sides of the equation giving,
-3 = 14
That is NOT true. Therefore, the answer is the equation is NEVER TRUE.

Name 4 decimals whose sum is 2.35

Sever21 [200]

Answer:

The values of 4 decimals whose sum is 2.35 will be:

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

Step-by-step explanation:

Name 4 decimals whose sum is 2.35

Let us consider that

a be first decimal

b the second decimal

c be the third decimal

d be the fourth decimal

According to the condition, we have to determine

$a\:+\:b\:+\:c\:+\:d\:=\:2.35$

As we have to name 4 decimals whose sum is 2.35.

So, taking the certain values of a, b, c and d as

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

The sum of a, b, c and d will be:

$0.35+0.68+0.81+0.51=2.35$

Putting the values of a, b, c and d in the equation $a\:+\:b\:+\:c\:+\:d\:=\:2.35$ .

$a\:+\:b\:+\:c\:+\:d\:=\:2.35$

$0.35+0.68+0.81+0.51=2.35$

$2.35 = 2.35$

Therefore, the values of 4 decimals whose sum is 2.35 will be:

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

Find the measures of the supplementary angles that satisfy each case.

seropon [69]

Answer:

67.5°, 107.5°

Step-by-step explanation:

For supplementary angles, their sum equals 180°.

Let x be the first angle and y be the second angle, then

x + y = 180°.

It is given that x = y + 45°.

So x + y = 180°

substituting x into the equation, we have

y + 45° + y = 180°

simplifying, we have

2y + 45° = 180°

collecting like terms, we have

2y = 180° - 45°

2y = 135°

dividing through by 2, we have

y = 135°/2

y = 67.5°

Since y = 67.5°

then x = y + 45°

x = 67.5° + 45°

x = 107.5°

john makes $8 an hour walkin dogs and 16 an hour as a math tutor this weekend he wants to work no more than 10 hours he also wan

lawyer [7]

This question can be solved using an Algebraic equation.

The system of equations is given as:

x + y ≤ 10

8x + 16y ≥ 96

Let's represent

x = number of hours he walks the dogs

y = number of hours he works as a maths tutor

John must work for no more than 8 hours walking the dog and 2 hours as a Maths tutor to earn at least $96.

Our system of equations is given as:

He wants to work no more than 10 hours.

No more is represented by the inequality "≤ " = Less than or equal to

x + y ≤ 10 ...........Equation 1

He also wants to earn at least 96.

At least is represented by the inequality" ≥" = Greater than or equal to

$8 × x + $16 × y ≥ 96

8x + 16y ≥ 96........Equation 2

Solving for the number of hours

x + y = 10

x = 10 - y

Substitute 10 - y for x in Equation 2

8(10 - y) + 16y = 96

80 - 8y + 16y = 96

Collect like terms

8y = 96 - 80

8y = 16

Divide both sides by 8

8y/8 = 16/8

y = 2 hours

Solving for x

x = 10 - y

x = 10 - 2

x = 8 hours

Therefore, John must work for no more than 8 hours walking the dog and 2 hours as a Maths tutor to earn at least $96.
