(Online schooling)

Answers

Answer 1
Answer:

Answer: 4 times m is equals to -8.

OR

4 times a number is -8

Step-by-step explanation:

Given algebraic equation: 4m =-8

which is equivalent to 4 times m= -8

Therefore ,the sentence to represent the given algebraic equation will be

4 times m is equals to -8.

OR, you can also write

4 times a number is -8, where m is the number.
Answer 2
Answer: 4 times a number is equal to negative 8

In the diagram, find the measure of Angle y and Angle x.

PLEASE HELP ME!!

Answers

Answer:

Part 1) The measure of angle x is 24°

Part 2) The measure of angle y is 66°

Step-by-step explanation:

step 1

Find the measure of angle m∠IKL

we know that

m∠JKI+m∠IKL=180° ----> supplementary angles (form a linear pair)

we have

m∠JKI=48°

substitute

48°+m∠IKL=180°

m∠IKL=180°-48°=132°

step 2

Find the measure of angle x

we know that

The triangle IKL is an isosceles triangle

so

m∠KIL=m∠KLI=x

Remember that

The sum of the interior angles of a triangle must be equal to 180 degrees

m∠IKL+2x=180°

132°+2x=180°

2x=180°-132°

x=24°

step 3

In the right triangle JIL

Angles x and y are complementary

so

x+y=90°

24°+y=90°

y=90°-24°

y=66°

If x is not equal to zero, what is the value of 4(3x)^2/ (2x)^2

Answers

we can write it like this:

(4*(3x)*(3x))/((2x)(2x))

if x isn't 0, we can divide both sides by x:

(4*(3x)*(3))/((2x)(2))

and again


(4*(3)*(3))/((2)(2))


and now we can calcuate

(4*9))/(4)

and divide both sides by 4.

We're left with 9!!


so the solution is 9!

Y = 2x -7
x + 2y = 1

Answers

easy
y=2x-7
sub 2x-7 for every y you se inother equation
x+2(2x-7)=1
x+4x-14=1
5x-14=1
add 14 both sides
5x=15
divide 5
x=3

sub back

y=2x-7
y=2(3)-7
y=6-7
y=-1

(3,-1) is solution

What is the sum of the arithmetic sequence 8, 14, 20 ..., if there are 22 terms?

Answers

Answer:

The sum of 22 terms of given AP = 1562

Step-by-step explanation:

Formula:-

Sum of n terms of AP,

Sₙ= (n/2)[2a + (n - 1)d]

To find the sum of 22 terms

Here. a = 8, d = 6 and n = 22

Sₙ= (n/2)[2a + (n - 1)d]

S₂₂ = (22/2)[2*8 + (22 - 1)*6]

  = 11[16 + 126] = 11 * 142 = 1562

Answer: I'm pretty sure its 1562
