Answer 1

Answer:

B. 3x and 8x

Step-by-step explanation:

if you look closely at this expression you'll notice that each polynomial is almost all different except for 3x and 8x because they share the same unknown variable. you couldn't choose 8 because that is just a whole number and all the other numbers contain a variable. and you couldn't choose 3y because y only affects the 3 in this expression whereas x affects 3x and 8x therefore the right answer is 3x and 8x which are the like terms.

Answer 2
B. They both have the same variable.

Answer:

  x = 8

Step-by-step explanation:

Corresponding segments are proportional.

  (3x +1)/10 = (7x -1)/22

  11(3x +1) = 5(7x -1) . . . . . . multiply by 110

  33x + 11 = 35x -5 . . . . . . eliminate parentheses

  16 = 2x . . . . . . . . . . . add 5-33x to both sides

Anyone know how to solve this?

Answers

Answer:

b = 22

Step-by-step explanation:

Here b represents the length of the hypotenuse, and 11 is the length of the side opposite the 30 degree angle.  We want to find the value of b.  We use the sine function here because we have the angle measurement (b), the angle 30 degrees and the "opposite side" 11:

sin 30 degrees = (1/2) = 11/b, which, if inverted, is 2 = b/11, or b = 22

Last month, Harri drove 850miles in his car. His car's fuel consumption is 45.6 miles per gallon petrol cost £1.09 per litre given that 8 pints=1 gallon work out how much Harri spent on fuel last month

Answers

Using proportions, it is found that Harri spent £76.91 on fuel last month.

What is a proportion?

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations, especially multiplication and division with the rates.

For this problem, we have that Harri drove 850 miles with a rate of 45.6 miles per gallon hence the number of gallons that Harri used is given as follows:

850/45.6 = 18.64 gallons.

Each gallon is equivalent to 3.78541 liters, hence the number of liters that Harri used is given as follows:

18.64 x 3.78541 = 70.56 liters.

The cost per liter was of £1.09, hence the amount that Harri spent during the last month is given as follows:

70.56 x 1.09 = £76.91.
