Evaluate 12x-3(3x-5)+24 when x = 2

Answers

Answer:

Step-by-step explanation: All we are doing here is inserting 2 in place of all the x variables. So that is written as 12(2)-3(3(2)-5)+24. Next, we follow the order of operations to solve

1) Multiply 3 by 2 and subtract by 5 inside the parenthesis = 12(2)-3-1+24

2) Multiply 12 by = 24-3+1+24

3) subtract 3 from 24 = 21+24

4) Add the final two terms = 45

Rafael writes an expression to represent “a number, n, decreased by thirty-one.” Then he evaluates that expression if n = 29. Which statements are true about the expression and its evaluation? Check all that apply.
The correct expression is 31 minus n.
This is a subtraction expression.
This is an addition expression.
To evaluate, substitute 29 for the variable in the expression.
To evaluate, substitute 31 for the variable in the equation.
To evaluate the expression, add 31 to 29.
The correct expression is n minus 31.
To evaluate the expression, subtract 31 from 29.

Daniel is going to buy a pizza.


He can choose one pizza variety, one extra topping and one pizza size.


He can choose from


23 different pizza varieties


18 different extra toppings


The total number of ways Daniel can choose the pizza variety, the one extra topping and the


pizza size is 3726


Work out the number of different pizza sizes that Daniel can choose from.

Answers

Answer:

9

Step-by-step explanation:

For each pizza variety, Daniel can choose 18 different toppings. Therefore, for 23 pizza varieties, Daniel can choose from 23 * 18 = 414 different combinations of varieties and toppings.

For each pizza size, Daniel can choose from 414 different combinations of varieties and toppings. Therefore, for n pizza sizes, Daniel can choose from n * 414 = 3726 combinations

414n = 3726

divide both sides by 414 to isolate the n

n = 9

solve the following equation: 0.4(g-2)+1.2=-(g-1)+2.9​

Answers

Answer: g = 2.5

Hope it helps!

Answer:

g = 2.5

Step-by-step explanation:

0.4(g - 2) + 1.2 = - (g - 1) + 2.9 ← distribute parenthesis on both sides

0.4g - 0.8 + 1.2 = - g + 1 + 2.9 ( simplify both sides )

0.4g + 0.4 = - g + 3.9 ( add g to both sides )

1.4g + 0.4 = 3.9 ( subtract 0.4 from both sides )

1.4g = 3.5 ( divide both sides by 1.4 )

g = 2.5

Hint: They are formed on a line.​

If 2 angles are formed on a line, then they make a supplementary / linear pair of angles, i.e, both the angles form 180°.

Here,

Angle A = 80°

Angle B = x°

So,

Angle A + Angle B = 180°

80° + x° = 180°

x° = 180° - 80°

x° = 100°

Answers

Answer:

x = 50 and y = 10

Step-by-step explanation:

The drawing shows several equal sides.  The triangles are a reflection of each other, so their angles will be the same.

Take the top and bottom angles:

2x + 5 and 3x - 45

They are equal, so:

2x + 5 = 3x - 45

-x = -50

x = 50

The angle y will have the same value as the one below it in the bottom triangle.  Add the angles in the lower triangle and since the sum of the angles in a triangle is always 180, we can say:

y + (8y-15) + (3x-45) = 180

Rearrange:

y  = 180 - (8y-15) - (3x-45)

y  = 180 - 8y + 15 - 3x + 45

9y = 180 + 15 - 3x + 45

Since x = 50:

9y = 180 + 15 - 3*(50) + 45

9y = 180 + 15 - 150 + 45

9y = 90

y = 10
