Which of these equations is NOT true?
A) 2(a + b) = a +b+a+b
C) (t-4) +6=t-10
B) 3y + 4y = 7y
D) x(5 + 9) - x = 13x

Answers

Answer 1

Answer:

C) (t-4) + 6=t-10

Step-by-step explanation:

2(a+b)= a+b+a+b

2(a+b)= 2a+b+b

2(a+b)=2a+2b

2(a+b) = 2(a+b)✅

(t-4)+6=t-10

t+2=t-10❌

3y+4y=7y

7y=7y✅

x(5+9)-x=13x

x(14)-x=13x

14x-x=13x

13x=13x ✅

(Urgent!! Please help) The average annual income for five salespeople last year was $54,200. Four of the salespeople earned these annual amounts: $58,125; $53,190; $48,975 and $56,000. What was the annual income of the fifth salesperson?

Answers

Answer:

54,710

Step-by-step explanation:

multiply the average by 5 to get the amout that they should all have togetehr (271,000) and the add the 4 people's money together (216,290) and then subtract them

The annual income of the fifth salesperson is $54710 if the average annual income for five salespeople last year was $54,200.

What is average?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

It is given that:

The average annual income for five salespeople last year was $54,200. Four of the salespeople earned these annual amounts: $58,125; $53,190; $48,975 and $56,000.

Let x be the annual income of the fifth salesperson:

$54,200 = ($58,125+$53,190+$48,975+$56,000+x)/5

271000 = 216 290 + x

x = $54710

Thus, the annual income of the fifth salesperson is $54710 if the average annual income for five salespeople last year was $54,200.

What is the value of x2 + (2y) ÷ (2w) + 3z for w = 2, x = 5, y = 8, and z = 3?

Answers

To find the value of x² + (2y) ÷(2w) +3z , first we substitute the values of w, x, y and z

5² + 2(8) ÷ 2(2) + 3(3)

To simplify this further, we have to apply the rule of BODMAS

(Applying the rule of BODMAS simply means when you have an equation, if its having bracket, you have to remove the bracket first, then you move to powers then you proceed to dividing then subtraction and then addition)

5² + 2(8) ÷ 2(2) + 3(3)

=25 +16 ÷ 4 +9

=25 + 4 +9

=38

Therefore the value of x² + (2y) ÷(2w) +3z is 38

A single die is rolled twice. Find the probability of rolling an odd
number the first time and a number greater than 4 the second time.

Answers

Step-by-step explanation and answer:

The 6 sides of the die are numbered 1,2,3,4,5,6

There are 3 odd and 3 even numbers

probability of an odd number on 1st roll is:

3/6=1/2

When you want A AND B probabilities, you multiply

the events A and B

The number less than 3 are 1,2, so the probability is:

2/6=1/3

so the probability of both events are going to be:

(1/2) *(1/3)=1/6

1/8 divided by ? = 1/40

fill in the question mark

Answers

Answer:

5

Step-by-step explanation:

1/8 divided by 5 equals 1/40

Answer:

[tex]\frac{\frac{1}{8}}{5}=\frac{1}{40}[/tex]

Step-by-step explanation:

Let 'x' be the number to which 1/8 had to be divided to get 1/40

so the equation becomes

[tex]\frac{1}{8}\div \:x=\frac{1}{40}[/tex]

[tex]\frac{\frac{1}{8}}{x}=\frac{1}{40}[/tex]

[tex]\frac{1}{8x}=\frac{1}{40}[/tex]

[tex]\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c[/tex]

[tex]1\cdot \:40=8x\cdot \:1[/tex]

[tex]40=8x[/tex]

switch sides

[tex]8x=40[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}=\frac{40}{8}[/tex]

[tex]x=5[/tex]

x=5 is the number.

Therefore,

1/8 divided by 5 = 1/40

i.e.

[tex]\frac{\frac{1}{8}}{5}=\frac{1}{40}[/tex]

SOLUTION CHECK

[tex]\frac{\frac{1}{8}}{5}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{c}=\frac{a}{b\cdot \:c}[/tex]

[tex]=\frac{1}{8\cdot \:5}[/tex]     ∵ [tex]\frac{\frac{1}{8}}{5}=\frac{1}{8\cdot \:5}[/tex]

[tex]=\frac{1}{40}[/tex]
