Please help me understand how to do the problem below

solve the problem as a  equation eg collect like terms

Step-by-step explanation:

Step-by-step explanation:

Sum of all the angles of  triangle = 180

∠A + ∠B + ∠C = 180

2x -3 +3x +4 +x -1 = 180

2x + 3x +x  - 3 + 4 - 1 = 180

6x + 0 = 180

6x = 180

x = 180/6

x = 30°

∠A = 2x -3 = 2*30 - 3 = 60 - 3 = 57°

∠B =  3x +4 = 3* 30 + 4 = 90 + 4 = 94°

∠C= x - 1 = 30- 1 = 29°

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
