Five is seven more than the product of two and a number. what is the number

1 answer:

3 0

Let n = the unknown number.

The phrase "five is" tells us to start the equation with "5 ="

"Seven more than" becomes "7 +"

"The product of two and a number" is 2n or (2 * n)

Put it all together and solve:
5 = 7 + 2n

5 = 7 + 2n
5 - 7 = 2n
- 2 = 2n
Divide each side by 2 to isolate the variable

- 1 = n

Your number is - 1

Answer:

r = 7 q - 34

Step-by-step explanation:

Solve for r:

-34 + 7 q - r = 0

Subtract 7 q - 34 from both sides:

-r = 34 - 7 q

Multiply both sides by -1:

Answer: r = 7 q - 34

-5=5(d+4)<br> Please give step by step

bekas [8.4K]

Answer:

first distribute the 5 to the d and 4
5(d+4) then becomes 5d+20
then subtract 20 from both sides of the equation
-5=5d+20 is now -25=5d
lastly divide 5 from both sides
-25=5d is now -5=d

Step-by-step explanation:

You need to use the law of sine for both of them

the law of sine is as follows:

$\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}$

Question 1:

$\frac{15}{\sin(64)}=\frac{10}{\sin(y)}\\y=36.81233927$

Question 2:

Let x= AB

Start by solving for the missing angle, 53

$\frac{8.4}{\sin(31)}=\frac{x}{\sin(53)}$

x= 13.02532494
