Answer:
5 x^2 - 32
Step-by-step explanation:
Simplify the following:
3 x^2 + 2 x^2 - 32
Grouping like terms, 3 x^2 + 2 x^2 - 32 = (2 x^2 + 3 x^2) - 32:
(2 x^2 + 3 x^2) - 32
2 x^2 + 3 x^2 = 5 x^2:
Answer: 5 x^2 - 32
Answer:
x = -22
Step-by-step explanation:
The given expression is :
-0.57x+0.27x = 6.6
We need to find the value of x.
x(-0.57+0.27) = 6.6
x(-0.3) = 6.6
So, the value of x is -22.
1500 divided by 100 is 15 .
Take into account the length of the right side of the figure is 10. Moreover, x is the hypotenuse of a right triangle. To find the value of x, use the sine function:
cos 45 = opposite side/hypotenuse
cos 45 = 10/x solve for x
x = 10/cos 45
x = 10/0.707
x = 14.14
with the previous value of x, you can find y. Again, consider the right triangle right side. x is the hypotenuse. Use the Pythagorean theorem to find y:
x² = 10² + y² solve for y and replace x
y² = x² - 10²
y² = (14.14)² - 100
y² = 200 - 100
y² = 100 apply square root both sides
y = 10
Hence, the values of x and y are 14.14 and 10 respectively
Answer:
51
Step-by-step explanation:
5 students travelled by car , leaving 158 - 5 = 153 students to travel by bus.
153 students travelled in 3 full buses, therefore
153 ÷ 3 = 51 students in each bus
