Five times the sum of a number and 7 equals 3

2 answers:

7 0

Hi there! :)
Let the number be x. Thus, the sum of a number and 7 would be x + 7. We can now set up the equation as follows:
5(x + 7) = 3;
5x + 35 = 3;
x = -32/5

Hope this helps!

The answer or number that you are looking for is -6.4. You can get this by dividing 3 by 5 which is equal to 0.6. Next you would subtract 7 to reverse the act of having added it. This will give you -6.4 which is what you are looking for.

Find x - y subtracted from 0

alexandr1967 [171]

The expression you want to simplify is 0-(x-y).
0-(x-y)
=-(x-y)
=-x+y

You just have to treat the negative sign in front of (x-y) as a -1 and distribute it to both x and -y.

The fraction was just to throw you off, it's not too hard if you look carefully since you get a whole number from it

All of the values follow the same formula rule. n= n x (n-1) / 2
Use this formula to find the number of segments.

Find the sine of ∠U. A)48/55 B)48/73 C)55/48 D)55/73

charle [14.2K]

Answer:

D) 55/73

Step-by-step explanation:

The question is on trigonometry. Sine of an angle is obtained using the SOH of SOHCAHTOA formula of trigonometry. SOH is an acronym for sine, opposite and hypotenuse. Sine of an angle is obtained from the ratio of opposite and hypotenuse of a given triangle. Thus, SOH

is denoted as stated below.

$sine \: \beta = \frac{opposite}{hypotenuse}$

Hence, given the above triangle,

$sine \: of \: angle \: u = \frac{ |bc| }{ |ab| } = \frac{55}{73}$

Therefore, the sine of angle u = 55/73 (D)

Solve the equality 2(4x+1 )< 3(2x-3)

Musya8 [376]

Answer:

Step-by-step explanation:

2(4x+1)<3(2x-3)

simplify to

8x+2<6x-9

we can add 9 to both sides and subtract 8x from both sides

11<-2x

divide by -2
