A is more because 1/4 is equal to 2/8 and 2/8 is less than 7/8 so you would have more than a minute
B is three minutes 2/8 goes into 7/8 three times

Applying properties to write equivalent expressions for 2x+5y+5(2x+5y)

levacccp [35]

Solving expression $2x+5y+5(2x+5y)$ we get $12x+30y$

Step-by-step explanation:

We need to solve the expression:

$2x+5y+5(2x+5y)$

Solving:

Multiplying 5 with terms inside the bracket:

$2x+5y+5(2x+5y)\\=2x+5y+10x+25y\\Combining\,\,like\,\,terms:\\=2x+10x+5y+25y\\=12x+30y$

So, Solving expression $2x+5y+5(2x+5y)$ we get $12x+30y$

Amanda think of a number, a. She subtract 4 then multiples the result by 2. Write an expression for her number?

algol13

(X - 4 ) x 2 = X

You subtract X from four then you get your answer next to multiply your answer by two resulting in an answer….. the answer is the expression I wrote above.

5+(−4)+(−7)+2 jijujuijuijuijujijuijuijuijiji

Maurinko [17]

Combine the terms. Note that: one positive and one negative sign results in a negative sign.

Simplify: 5 + (-4) = 5 - 4 = 1

1 + (-7) = 1 - 7 = -6

-6 + 2 = -4

-4 is your answer

Answer:

x = 76.9

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side / adj side

tan 70 = x/28

28 tan 70 = x

x=76.92936

Rounding to the nearest tenth

x = 76.9

PLEASE HELP!! How many solutions can be found for the equation −4x − 11 = 2(x − 3x) + 13?

PilotLPTM [1.2K]

Answer: $No~Solution$ $s$

Step-by-step explanation:

Let's factor then solve to find the complex solutions.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : $-4x-11=2(x-3x)+13$

Equations that are never true:

$1.1 ~~~~ Solve : -24 = 0$

This equation has no solution.

A non-zero constant never equals zero.

Therefore your answer is $No~Solution$
