90-80*2-2
plz helpppppppppppppppppp
Answer:
18
Step-by-step explanation:
90-80=10
10*2=20
20-2=18
Answer:
90-80 x 2-2 = 0
Step-by-step explanation:
Firstly. subtract 80 from 90 to get 10.
90-80= 10
Then subtract 2 from 2, to get 0.
2-2=0
Lastly, for your answer multiply 10 by 0 to get 0.
10 x 0 = 0

Rewrite the quadratic function from standard form to vertex form.
f(x)x^2+6x-5
Answer:
[tex]y = {(x + 3)}^{2} - 14[/tex]
Step-by-step explanation:
The original equation
[tex] f(x) = {x }^{2} + 6x - 5[/tex]
vertex form
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
solve for the x coordinate of the vertex, h
[tex]x = h = - \frac{b}{2a} = - \frac{6}{2(1)} = - \frac{6}{2} = - 3 \\ x = h = - 3[/tex]
substitute -3 back into the original equation to solve for y
[tex]y = { (- 3)}^{2} + 6( - 3) - 5 \\ y = 9 - 18 - 5 \\ y = 4 - 18 \\ y = k = - 14 [/tex]
substitute h and k values into the vertex form
a = 1 So we can omit it
[tex]y = {(x - ( - 3)}^{2} - 14 \\ y = {(x + 3)}^{2} - 14[/tex]
Two angles are supplementary if their sum is 180". The larger angle measures eight degrees more than three times the measure of a smaller angle. If x represents the measure of the smaller angle and these two angles are supplementary, find
the measure of each angle
Please help give the smaller and bigger angle measure
Answer:
Step-by-step explanation:
2 angles are supplementary if their sum is 180 degrees. The larger angle measures eight degrees more than three times the measure of a smaller angle. If x represents the measure of the smaller angle and these two angles are supplementary, find the measure of each angle. I have the answer but do not know how to get it 43 degrees & 137 degrees
Let the smaller angle be x
The larger angle will be 3x+8
X+3x+8=180
4x=180-8=172
X=172/4
X=43
3*43+8= 137

prove that 5^(2n - 1) is divisible by 8
Your teacher must have made a typo somewhere. The expression 5^(2n-1) is not divisible by 8.
The expression 5^(2n-1) is composed of 2n-1 copies of "5" multiplied together. The key here is that 5 is the only unique prime factor of this number.
On the other hand, 8 = 2*2*2 = 2^3 showing that 2 is the only prime factor for this number. At this point, we can see that there's no way that 5^(2n-1) is divisible by 8. It all comes down to the clash of the primes 5 and 2 not matching up, and having nothing in common.
Let's consider a few concrete examples:
If n = 1, then 5^(2n-1) = 5^(2*1-1) = 5^1 = 5 which is not divisible by 8. The number 5/8 = 0.625 isn't an integer.If n = 2, then 5^(2n-1) = 5^(2*2-1) = 5^3 = 125 which is also not a multiple of 8. The number 125/8 = 15.625 isn't an integer.I'll let you try other natural numbers for n, and you'll find that [tex]\frac{5^{2n-1}}{8}[/tex] isn't an integer.

Which explains the number of decimal places in the product 0 . 42 × 3 . 8 × 10 . 51 ? A. The greatest number of decimal places in any of the factors is 1. So, the product will have 1 decimal place. B. The greatest number of decimal places in any of the factors is 2. So, the product will have 2 decimal places. C. There are a total of 4 decimal places in the factors. So, the product will have 4 decimal places. D. There are a total of 5 decimal places in the factors. So, the product will have 5 decimal places.
Answer:
D
Step-by-step explanation:
if you place the decimals ontop of each other like this
0.42
3.8
10.51
and count the numbers behind the decimal of each decimal which is
4, 2, 8, 3, 1
meaning that your decimal place would be 5 places to the left of your answer when you multiply
Answer:
D
Step-by-step explanation:
here are a total of 5 decimal places in the factors. So, the product will have 5 decimal places.

guys pls help me!!!!!!!
Answer:
The answer is t = 17
Step-by-step explanation:
Sum of angles on a straight line = 180⁰
(2t -7) + 90 + 49= 180
(2t -7) +139 = 180⁰
2t -7) = 180 - 139
2t - 7 = 41
2t = 41 - 7
2t = 34
Divide both sides by 2
t = 17

= 51/85 × 100%
= 51/17 × 20%
= 3 × 20%
= 60%
If 25% of $2000 is spent on food,how much money is spent on food?
Answer:
$500
Step-by-step explanation:
Simply change the 25% into a decimal which is 0.25 and multiply $2000.
Or you can change 25% into a a fraction which is 25/100 and simplify giving 1/4. Then simply multiply $2000 by the fraction: 2000/1×1/4. Cross multiply which is 2000×1/1×4=2000/4. Now simply divide 2000 by 4 and you get 500 as your answer.

Find two consecutive odd integers such that
4 times the smaller integer is 19 less than 5
times the larger integer.
Answer:
9 and 11
Step-by-step explanation:
let the consecutive odd integers be n and n + 2 , then
4n = 5(n + 2) - 19 , that is
4n = 5n + 10 - 19 ( subtract 5n from both sides )
- n = - 9 ( multiply both sides by - 1 )
n = 9 and n + 2 = 9 + 2 = 11
The 2 integers are 9 and 11
