3x – 5 = 1

Answer:

see explanation

Step-by-step explanation:

Expressing ratios in fractional form, then

[tex]\frac{a}{c}[/tex] = [tex]\frac{a}{b}[/tex] × [tex]\frac{b}{c}[/tex] = [tex]\frac{2}{3}[/tex] × [tex]\frac{5}{6}[/tex] = [tex]\frac{1}{3}[/tex] × [tex]\frac{5}{3}[/tex] = [tex]\frac{5}{9}[/tex]

That is a : c = 5 : 9

[tex]\frac{1}{2}(4x-8)=\frac{1}{2}\cdot4x-\frac{1}{2}\cdot8=2x-4[/tex]

Hope this helps :)

[tex]\frac{1}{2}(4x-8)=\frac{1}{2}\cdot4x-\frac{1}{2}\cdot8=\\\\=\frac{4x}{2}-\frac{8}{2}=\boxed{2x-4}[/tex]

Answer:

3 5/18 cups of oatmeal are left in the container.

Step-by-step explanation:

4/9 times 5 = 20/9

5 1/2 = 11/2

11/2 - 20/9 = 99/18 - 40/18

= 59/18

= 3 5/18

Answer:

  b = 20/7

Step-by-step explanation:

The slope of the first line can be found by solving for y:

  by = -5x +6 . . . . . . add 6-5x

  y = -5/b +6/b . . . . . divide by b

The slope is -5/b.

The slope of the second line can be found by solving for y:

  7y = 4x +7

  y = 4/7x +1 . . . . . . divide by 7

The slope is 4/7.

For the lines to be perpendicular, the product of these slopes must be -1:

  (-5/b)(4/7) = -1

  -20/(7b) = -1 . . . . simplify

  b = 20/7 . . . . . . . multiply by -b

The lines will be perpendicular when b = 20/7.

Answer: (-2, 4)

Concept:

There are three general ways to solve systems of equations:

Here we are going to use substitution since the variable [y] is being isolated in both equations.

Solve:

Given equations

y = -x + 2

y = -3x - 2

Using the method of substitution to combine the equations

-x + 2 = -3x - 2

Add 3x on both sides

-x + 2 + 3x = -3x - 2 + 3x

2x + 2 = -2

Subtract 2 on both sides

2x + 2 - 2 = -2 - 2

2x = -4

Divide 2 on both sides

2x / 2 = -4 / 2

[tex]\boxed{x=-2}[/tex]

Find the y value

y = -x + 2 →→→ Given expression

y = -(-2) + 2 →→→ Substitute values into the expression

y = 2 + 2 →→→ Simplify the value

[tex]\boxed{y=4}[/tex] →→→ SImplify by addition

Hope this helps!! :)

Answer:

x-int=0.5 & y-int=3.4 you option are wrong

Answer:

Tessa's expression is false because -7 times -4 is positive 28, not -28.

Bernette's expressionis false because you must distribute the -7 before subtracting 7 from 2 (peMdas)

Lucy's expression is true because she correctly distributed the -7 to each of the terms in the parentheses and used PEMDAS.

2-21x+28

The equivalent expression for the given expression is 2-21x+28.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Tessa:

2-7(3x-4)=2-21x-28

Tessa's equivalent expression is wrong. Because -7×(-4)=28 not -28.

Bernette:

2-7(3x-4)=-5(3x-4)

Bernette's equivalent expression is wrong. Because, you can not 2 and 7, since 7 is multiplied to the term 3x-4

Lucy:

2-7(3x-4)=2-21x+28

Lucy's equivalent expression is correct.

Therefore, the equivalent expression is 2-21x+28.

Step-by-step explanation:

6 - 5(2x-3) = 4x + 7

-5(2x-3) = 4x + 1

-10x + 15 = 4x + 1

-14x = -14

14x = 14

x = 1

Answer:

FIRST !!!!

anything raised to the zero power is equal to 1 (one)

so I think that three is wrong....

as for 4....

3/3 = 1    5/5= 1    x/x = 1 anything divided by itself is one...

so you have 1*1 = 1

as for 5 ... it is the same as for ALL THE STUFF on the TOP

gets cancelled by the SAME items on the BOTTOM ???/??? if they are the same the answer is 1

NOTE if ??? = zero then we have a problem .. you can't divide by zero that is an exception

Answer: 21

Step-by-step explanation:

First we have to find LCM (lowest common multiple) of the given number, i.e 700.

LCM = 2 × 2 × 5 × 5 × 7 = 700

now, let's add 7 to 700

We get the required number as 707

Answer:

25

Step-by-step explanation:

The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

looks like the answer C. Thousands.

In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively.

In a positional numeral system, a numerical digit is a single sign that can be used singly or in combination to represent numbers.

A digit is a part of a set that, when combined, makes up a numeration system.

For example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are digits.

The place value of a general abcd digit is given by

d = ones

c = tens

b = hundreds

a = thousands

So,

In the given number 72,204

4 = ones

0 = tens

2 =  hundreds

2 = thousands

7 = hundred thousand

Hence "In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively".
