Simplify 2(5x-3)-(2x+4), 24x-12y+40÷4, (2x)(3y)+2(-xy)

Answers

Answer 1

Answer: $2(5x-3)-(2x+4)=2\cdot5x-2\cdot3-2x-4\n\n=10x-6-2x-4=8x-10\n\n\n(24x-12y+40):4=24x:4-12y:4+40:4\n\n=6x-3y+10\n\n\n(2x)(3y)+2(-xy)=6xy-2xy=4xy$

A scale model of a building is 2.3 feet high. The ratio of the height of the model to the height of the building is 11:56. How tall is the building, in feet?

Answers

2.3 ------------ 11
x ------------ 56
then x= (2.3x56)/11

also easier would be just to multiply by 56/11.

The plaid flannel shirt that you have
wanted for months is now on sale at the mall for $35. Sales tax at the
mall is 7%. Before you leave to buy the shirt, you see an ad for the
same shirt for $30 with a sales tax of 9.5% at a shop 20 miles away.
Decide which shirt is the better buy and tell why. Can you think of one
reason that would make the more expensive shirt a better buy?

Answers

The shirt that costs 35.00 is the better buy because even though the shirt is more expensive than the other, it also has less tax. Also the shirt is local which saves you money on gas and wear and tear on your vehicle. In the end the 35.00 shirt is your smartest bet!

What is called co-ordinate?

Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).
There are several coordinate schemes commonly used by mathematicians, scientists, and engineers.

What is co-ordinate with example?

A set of values that show an exact position.
On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down.
Example: the point (12,5) is 12 units along, and 5 units up.

What is the co ordinate formula?

One of the important formula of coordinate geometry is the equation of the straight line which is y = mx + c.
Here m is the slope and c is the y-intercept (tan θ = m, here θ is the angle that the line makes with the positive x-axis).

What is coordinate of a point?

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane.
Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis.
The coordinates of a given point represent how far along each axis the point is located.
