They are NOT because supplementary angles add up to 180

Angles 1 and 2 add up to 90 degrees. Those are called complementary angles, not supplementary angles.

Answer: False

The sum of 444 consecutive integers is 326326326.<br> What is the second number in this sequence?

Nookie1986 [14]

Answer:

Step-by-step explanation:

Let's first figure out what the first number is and use that to solve for the next. The problem states that the numbers are consecutive. So the 2nd number word be 1 plus the first.

The sum of 4 consecutive numbers:

1st = x

2nd = x + 1

3rd = x + 2

4th = x + 3

The sum of 4 consecutive number is 326.

1st + 2nd + 3rd + 4th = 326

x + (x + 1) + (x + 2) + (x + 3) = 326

Combine like terms:

4x + 6 = 326

Then we subtract 6 from both sides to isolate 4x:

4x + 6 - 6 = 326 - 6

4x = 320

Then we divide both sides by 4 to isolate x:

4x/4 = 320/4

x = 80

So the first number is 79

Now to get the second, let's just add 1.

80 + 1 = 81

Let's check if our answer would be correct:

80 + 81 + 82 + 83

= 326

£940 is divided between gavin, jim & Krutika so that gavin gets twice as much as jim, and jim gets three times as much as kr

Zielflug [23.3K]

Answer:

$282

Step-by-step explanation:

We can think of it as an equation system. Lets find out the equations.

There are 3 people: Krutika, Gavin and Jim. Lets call k Kutrika's money and g and j Gavin's and Jim's money respectively.

So, as Gavin gains twice as Jim we can say that:

g = 2j

Then, as Jim gets 3 times more than Kutrika:

j = 3k

And, as the whole sum is 940:

k + j + g = 940.

Notice that both Kutrika's and Gavin's money have a relation to Jim's money, so we can try to write them as function of Jim's money.

If we part from j = 3k and divide both sides by 3:

j/3 = k

So, using this last equation and g = 2j, replacing in the equation that sums the money of everyone:

k + j + g = 940

j/3 + j + 2j = 940

Putting together all the terms that have j imply using 3 as common denominator:

j/3 + 3j/3 + 6j/3 = 940

10j/3 = 940

Dividing both sides by 10/3 (or multiplying by 3/10):

j = 940/ (10/3) = 282

So, Jim has $282. Now we can use the relations we defined to find k and g:

k = j/3 =$94

g = 2j = $564

Please help! The question is in the pic!

lozanna [386]

Answer:

B. -x + 8

Step-by-step explanation:

Given expression

$\dfrac{8-4(x-6)}{4}$

Consider the numerator $8-4(x-6).$

First, use distributive property:

$8-4(x-6)=8-(4x-24)$

Open the brackets:

$8-(4x-24)=8-4x+24$

Combine the like terms:

$8-4x+24=(8+24)-4x=32-4x$

Again use distributive property:

$32-4x=4\cdot 8-4x=4(8-x)$

Now, the expression is

$\dfrac{4(8-x)}{4}=8-x\ \text{or}\ -x+8$

A pair of shoes is on sale for 30% off. The original price is p. Which expression can be used to find the price of the shoes aft

Sidana [21]

The correct option is b which is 0.70p.

Given to us,

original price of shoes = p,

Discount on shoes = 30%

As we know after giving the discount the value of the shoes will be 70% of the original price, therefore,

$\bold{p=100\%\ price\ of\ shoes = \dfrac{100}{100}\times p = p}$

After 30% discount,

$\bold{p=(100\%-70\%) price\ of\ shoes}$

$\bold{p=70\%\ price\ of\ shoes = \dfrac{70}{100}\timesp= 0.7p }$

Hence, the correct option is b which is 0.70p.
