Answer:

Firstly you have to divide by 2 to get 't' so -4/2=-2

2/2=1

so the simplified inequality= -2<t<1

< and > are both illustrated as hollow circles so on a number line put a hollow circle on -2 and 1 and attach with a line

QRST is a parallelogram. Find x and y.

Wewaii [24]

In parallelograms, opposite sides are congruent, meaning that they are the same lengths. So, we have:

y - 4x = 9

-x + 4 = y

Add x to both sides of the second equation:

y + x = 4

y - 4x = 9

This is a system of linear equations. Solve by eliminating the y and subtracting the two equations:

5x = -5

x = -1

Use x to solve for y:

y + (-1) = 4

y = 5

So, x = -1 and y = 5.

The sum of two numbers is 21. The larger number is 6 less than twice the smaller number. Find the two numbers.

Vesnalui [34]

Hey there! :D

21= 2x-6+x

21=3x-6

27=3x

x=9

The smaller number is 9.

The larger number is:

9*2= 18 18-6= 12

The larger number is 12.

I hope this helps!

2 thousands 7 tens divided by 10 equal

Shkiper50 [21]

The answer is 207 or 2 hundreds 7 ones in unit form or two hundred seven in word form.

<h3>Further explanation</h3>

2 thousands 7 tens are a unit form. The standard form is 2,070.

Explanations and an example of questions about the four types of number forms can be found at brainly.com/question/4725342.

The key problem is working out the value of 90,000 divide by 10. This is a division operation.

$\boxed{2,070 \div 10 = ?}$

Option-1

Both numbers are divided by 10.

$\boxed{2,070 \div 10 = 207 \div 1}$

The result is

$\boxed{2,070 \div 10 = 207}$

Option-2

Division operations can be written as fractions, like this.

$\boxed{\frac{2,070}{10} = ?}$

The numerator and denominator are both divided by 10, or 'cross out a zero from both'.

$\boxed{\frac{207}{1} = ?}$

The result is

$\boxed{2,070 \div 10 = 207}$

- - - - - - -

If x is divided by y equals z, then x is equal to y multiplied by z.

$\boxed{If \ x \div y = z \ or \ \frac{x}{y} = z, then \ x= y \times z}$

Let's prove it!

$\boxed{If \ 2,070 \div 10 = 207 \ or \ \frac{2,070}{10} = 270, then \ 2,070 = 10 \times 207}$

This is proven.
