(3z+1)+5+7z) Step by step explanation needed

Answers

Answer 1

Answer: 10z + 6

Step-by-step explanation:

this is a short problem.. sometimes you would need to distribute, but since there is no number in front of parenthesis you can just get rid of them

that gives you: 3z + 1 +5 + 7z

now from here we combined liked terms

7z + 3z = 10z

1 + 5 = 6

so that gives you: 10z + 6

Help please!! Help me with this triangle

Answers

Answer:60°

Step-by-step explanation: First, think about the rule of the degrees for all triangles. Angles must equal 180°.

Second, because all angles must equal 180°, see that the triangle given has equal sides (assuming this, because no other measurements are given).

Equilateral triangles have equal angles, meaning 60° for each angle.

if y(x) = 5x-2 and g(x) = 2x + 1, find (f + g)(x).

Answers

Answer:

(f + g)(x) = 7x - 1

Step-by-step explanation:

Given :  f(x) = 5x – 2 and g(x) = 2x + 1

We have to find  (f + g)(x)

Consider  (f + g)(x) = f(x) + g(x)

Also, given  f(x) = 5x – 2 and g(x) = 2x + 1

Substitute, we have,

f(x) + g(x) = 5x - 2 + 2x + 1

LIKE TERMS are terms having same variable with same degree.

Simplify by adding like terms,  we have,

f(x) + g(x) = 5x + 2x - 2  + 1

f(x) + g(x) = 7x  - 1

Thus, (f + g)(x) = 7x - 1

3) In June a gallon of gasoline cost $2.75. In July the price increased to
$2.92. What is the percent of increase of a gallon of gasoline from June to
July? Round to the nearest tenth.

Answers

Answer:

6.2%

Step-by-step explanation:

Hard to explain, but easy. Take your new value, and subtract your initial (starting) value from the new value. In this case, it would be 2.95-2.75= 17. You now can take you difference (17) and divide it by the initial value, so 17/2.75. This gives you 6.181818182. Round to 6.2%

Simplify 5a – (2a + 6)

Answers

Answer:

Step-by-step explanation:

Add '-2a' to each side of the equation.

5a + -2a = -6 + 2a + -2a

Combine like terms: 5a + -2a = 3a

3a = -6 + 2a + -2a

Combine like terms: 2a + -2a = 0

3a = -6 + 0

3a = -6

Divide each side by '3'.

a = -2

Simplifying

a = -2

5a -2a -6

3a -6

The aquarium opened at 8.00 am . In the first hour 140 people purchased admission tickets . In the second hour 25 % more people purchased admission tickets than the first hour . Each ticket cost 15.25 . What was the total amount of money paid for all the tickets purchased in the first two hours please help

Answers

Answer:

Total income= $4,083.75

Step-by-step explanation:

First, we need to calculate the total number of people that enter the aquarium in the first two hours.

1st hour= 140

2nd hour= 140*1.25= 175

Total number of people= 315

Now, we can determine the total amount of money earned:

Each ticket cost 15.25.

Total income= 315*15.25

Total income= $4,083.75
