Answers

Answer:

Let's solve for x.

4x+5y=7

Step 1: Add -5y to both sides.

4x+5y+−5y=7+−5y

4x=−5y+7

Step 2: Divide both sides by 4.

4x/4=−5y+7/4

x=−5/4 y+ 7/4

Answer: for the first one x=−5/4 y+ 7/4

3x−2y=−12

Step 1: Add 2y to both sides.

3x−2y+2y=−12+2y

3x=2y−12

Step 2: Divide both sides by 3.

3x/3=2y−12/3

x=2/3y−4

Answer:

x=2/3y−4

Answers

Answer:

Step-by-step explanation: The first one would be -40 X 30. The parentheses around -25 turns it into a positive. And 5 make you round up

For 2, the -18 turns into a positive 18 bc of the parentheses. So round up to 20. Round 38 up to 40. 20 x 40

For 3, the negative 16 turns positive, making the equation -21 x 9 x 16. Round them to -20, 10, and 20. The equation is -20 x 10 x 20. Hope this helps!

A person invests 9000 dollars in a bank. The
bank pays 6.5% interest compounded daily.
To the nearest tenth of a year, how long
must the person leave the money in the bank
until it reaches 31100 dollars?

Answers

Answer:

19 years approx

Step-by-step explanation:

Given dta

P= $9000

r= 6.5%

A= $31100

Calculate time, solve for t

t = ln(A/P) / r

substitute

t= ln(31100/9000)/0.06.5

t= ln(3.45)/0.06.5

t= 1.23/ 0.065

t= 18.92

Hence the time is 19 years approx

I need help with this last problem please

Answers

Answer:

25

Step-by-step explanation:

12+13=25 so 25x5=125 and 125 divide 5=25

I'm on computer so examples will look weird so I will label them.

Answer:

Your answer will be 25.

Step-by-step explanation:

1. You will rewrite the division as a fraction

Ex:    5 × (12+13)

     ____________

               5

2. Cancel the common factor which is 5 so you will cross out the 5's

3. Then you would divide the (12+13) by 1

4. Finally you would add the 12 and the 13 to get 15.

I hope this helps.   :  )

how to write a number increased by 11 is eaqual to twice the number decreased by 12

Answers

Answer: The number is 23

Step-by-step explanation:

Let x be the [number]

Rephrase the expression

a number increased by 11 is equal to twice the number decrease by 12

x+11=2x-12

Add 12 on both sides

x+11+12=2x-12+12

x+23=2x

Subtract x on both sides

x+23-x=2x-x

x=23

Hope this helps!! :)

If m<1 is 68° and m<3 is (3x - 7)º, what is x?

A. 25
B. 26 1/3
C. 49
D. 140

Answers

Answer:

C. 49.

Step-by-step explanation:

The measure of the angle below <1 = 68 degrees (vertical angles).

m < 3 = 72 + 68         External angle of a triangle theorem.

m < 3 = 140

3x - 7 = 140

3x = 147

x = 49.

Answer:

C

Step-by-step explanation:

The angle at the top of the triangle is vertical to ∠ 1 and congruent

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ 3 is an exterior angle of the triangle, then

3x - 7 = 72 + 68 = 140 ( add 7 to both sides )

3x = 147 ( divide both sides by 3 )

x = 49 → C
