This means it’s 6(3)^2. The PEMDAS process will help in this situation. Since exponents (E) come before multiplication (M), you would raise 3 to the 2nd power first. 3^2 is the same as 3 times 3, which equals 9. Now, you can multiple 6 by 9, which would result with 54. 54 is your answer!
Step-by-step explanation:
i. (2x+10)+(3x+5)+(2x+40) = 360
2x+3x+2x+10+5+40= 360
7x+55 =360
7x=360-55
<u>7x</u>= <u>3</u><u>05</u>
7. 7
x= 43.57=43.6
ii. 2x+10= 180
2x=180-10
<u>2</u><u>x</u>= <u>1</u><u>7</u><u>0</u>
2. 2
x=85
3x+5 =180
3x=180-5
<u>3</u><u>x</u>=<u>1</u><u>7</u><u>5</u>
3. 3
x= 57.5
2x+40=180
2x=180-40
<u>2x</u>=<u>140</u>
2. 2
x= 70
From the above 3x+5 which is 57.5 is the smallest interior angle of the triangle
iii. The largest interior angle of the triangle is 2x+10 which is 85
Answer:
1. n = 13
2. x = -30
3. y > -18
4. n < -0.75
5. 101 t-shirts
Step-by-step explanation:
1. multiply both sides by 2, then add both sides by 2, making n = 13
2. divide both sides by -3, then subtract both sides by 5 making x = -30
3. divide both sides by -2, when dividing by a negative number, you need to switch the inequality sign to the other side
4. divide both sides by 4, then divide by -2(you need to switch the inequality sign to the other side), then add -8 and 2.5, then add 5.5 to both sides
5. the equation is 150 = 5x - 45. 45 is because they have already earned it, and 5x is how much each shirt will cost. The solution is then 101.
Hope this has a helped a little at least :P
