Let ' a number ' = x

twice a number = 2x

The sum of 2x and three = 2x + 3

...equals five: 2x + 3 = 5

Find the number

2x + 3 = 5

Isolate the x. Do the opposite of PEMDAS. Note that because of the equal sign, what you do to one side, you do to the other.

Subtract 3 from both sides
2x + 3 (-3) = 5 (-3)

2x = 5 - 3

2x = 2
divide 2 from both sides
2x/2 = 2/2

x = 2/2

x = 1

hope this helps

Do they mean like give you an expression/equation or to tell them what kind. For example, “Distribution, Combine like terms, Substitution,etc.”

say the  is 3 two thirds of  3 is 2 and so 2+4=6

$22.08 Step-by-step explanation: As long as the night power is not greater than 50%, then the rate is$8.71365.

The day power plan is $13.3672, according to the narration the sum of both variable is required, which is$22.08085.

you turn that into 2/3*x +4=7 i belive and then you simply just solve for X

X=4.5

i could be wrong though i plugged it into my calculator and got 4 1/2

2n + 3 = 5
2n = 2
n = 1
the sum of 2 times a number and three means you add 2n + 3 and since it is equal to 5 you then solve for n.

A.
(0,00
(2.6,7.9)
(4.8,12.4)
(9.7,15.1)

b.
well, the points don't look like they are on the line but they actually are (plot twist)

so
since (0,0) is on th egarph

0=a(0)²+b(0)+c
0=c
so
f(x)=ax²+bx+0 or
f(x)=ax²+bx

find a and b
sub points

(2.6,7.9)
7.9=a(2.6)²+b(2.6)
7.9=6.76a+2.6b

(4.8,12.4)
12.4=a(4.8)²+b(4.8)
12.4=23.04a+4.8b

use those 2 equations
7.9=6.76a+2.6b
12.4=23.04a+4.8b

eliminate b
multiply first equation by -4.8 and 2nd by 2.6 and add them
-37.92=-32.448a-12.48b
32.24=59.904a-12.48b +
-5.68=27.456a+0b

-5.68=27.456a
divide both sides by 27.456
(-5.68/27.456)=a
find b

12.4=23.04a+4.8b
12.4=(-130.8672/27.456)+4.8b
12.4+(130.8672/27.456)=4.8b
(12.4+(130.8672/27.456))/4.8=b

da equation is
$y= \frac{-5.68}{27.456} x^2+ \frac{12.4+\frac{130.8672}{27.456}}{4.8}x$

c. the roots are found with your calculator
the roots are at x=0 and x=17.287323943662
so very close to the target but not exactly on it
if the target has a radius of 0.287323943662 or more then it will hit the target
