Step-by-step explanation:

Answer:

Computer: $620

Printer: $310

Step-by-step explanation:

c + p = 930

c = 2p

c = cost of the computer

p = cost of the printer

replacing the second eq. in the first eq.

2p + p = 930

3p = 930

p = 930/3

p = 310

from the second eq.

c = 2p

c = 2*310

c = 620

Check

from the first eq.

620 + 310 = 930

Answer:

There is no answer from my working the answer should be 55÷2

The value of x in the expression is 55/2 or 27½

From the question given above, we obtained:

The value of x can be obtained as follow:

(x – 3)2 = 49

Clear the bracket

2x – 6 = 49

Collect like terms

2x = 49 + 6

2x = 55

Divide both side by 2

x = 55 / 2 or 27½

Thus, the value of x is 55/2 or 27½

Answer:

All sides are equal

Step-by-step explanation:

Think: equilateral is equal so this must mean that something on the triangle has to be all equal.

The fractions which are equivalent to 1/2 are 2/4, 3/6, 4/8, 6/12 etc. Equivalent fractions have same value in reduced form.

Answer:

PROOF FOR THE "PROVE" SECTION:

As linear pairs, angle 2 and 3 are supplementary to each other. Angle 1 is equal to angle 2, as they are both same-side interior angles. Therefore, angle 1 and angle 3 are also supplementary.

Filling in the missing blanks:

S1. Angle 1, Angle 2, Angle 3

S2. Angle 1 and Angle 2

R3. Congruent (___)

R5. supplementary angles

S7. Angle 1 = Angle 2, so Angle 1 can be substitued in for Angle 2 in any equation, and Angle 2 can be substitued for Angle 1 in any equation as well (they can replace each other, like x=y & y=x or a=b & b=a)

Hope this helped! Have a great day (pls mark brainliest)!!

Answer:

You are filipino or not I need filipino women

Answer:

Step-by-step explanation:

we see that y = -3x-3

substitute that into the other equation to get

-3x-3 = 2x+7

-5x = 10

x = -2

so, y = -3(-2)-3 = 3

check to make sure (-2,3) solves both equations.

Answer:

x = -3 or x = 2

Step-by-step explanation:

Given that,

x ( x - 2 ) + 3 ( x - 2 ) = 0

( x + 3 )  (  x - 2 ) = 0

So,

( x + 3 ) = 0                                ( x - 2 ) = 0

x + 3 = 0                                     x - 2 = 0

x = 0 -3                                        x = 0 + 2

x = (-3)                       or               x = 2
