How do you solve -8= (×+11) ÷ -2

Mathematics
1 answer:
Elena-2011 [213]3 years ago
4 0

Answer:

Isolate x to get the answer.

Step-by-step explanation:

Cancel out the 2 on the left by multiplying both sides by 2.

-8 = (x + 11) / 2

turns into

-16 = (x + 11)

Next, cancel out the 11 by subtracting 11 on both sides.

-16 = (x + 11)

turns into

-27 = x

____________________________________________

Verify the answer:

([-27] + 11) / 2 = -8 ✔

Can someone help with number 20
enyata [817]

Answer:B: 36°


Step-by-step explanation:

We know that ∆ABC is isoceles, making (angle)<ABC and <BCA congruent because base angles of isoceles triangles are congruent.


Because we have parallel lines, we can look for alternate interior angle pairs. <BCA is congruent to <DAC because they're alternate interior angles.


If <BCA is x then so is <ABC.


Since triangles add up to 180° we can add all of the angles (3x+x+x) and set it equal to 180.

3x+x+x=180

5x=180

x=36


If we were looking for <BAC we would plug that back in and solve, but we're looking for <BCA which is equal to x, therefore m<BCA=36°

Use the substitution method to solve the system of equations
PilotLPTM [1.2K]

You solve the substitution method to solve a system of equality by expressing one variable in terms of the other using one equation, and then plugging this expression in the other(s).

In this case, the first equation gives us a way to express n in terms of m. So, we can replace every occurrence of n in the second equation with the given formula.

The result is

14m+2n=-8 \iff 14m+2(-7m-4)=-8 \iff 14m-14m-8=-8 \iff -8=-8

So, the second equation turned to be an equality, i.e. an equation where both sides are the same.

This implies that the system has infinitely many solutions, because every couple (n,m) such that n=-7m-4 is a solution to the system, because it satisfies both equations: the first is trivially satisfied, whereas the second is an identity, and as such is satisfied by any value of the variable.

Horses are to race over a certain english meadow for a distance of 6.7 furlongs. what is the race distance in units of (a) rods
Law Incorporation [45]

we are given

distance=6.7 furlongs

(a) In rods

we know that

1 furlong=40.0001 rod

we can multiply both sides by 6.7

6.7*1 furlong=6.7*40.0001 rod

6.7furlong=268.00067 rods..............Answer

(b) In chains

we know that

1 furlong=10 chains

we can multiply both sides by 6.7

6.7*1 furlong=6.7*10 chains

6.7furlong=67 chains..............Answer
