Answer:
my answer is 17 5/5
Step-by-step explanation: so what i did was that i add 13 and 4/5 but i can't add like that so i put 13/1 + 4/5 and they don't have the same denominator so i did 1 x 5 so if i do it on the bottom i have to do it on the top and so i did 13 x 5 and 13 x 5 is 65 and 1 x 5 is 5 and so my new fractions are 65/5 + 4/5 and i add both them and got 69/5 so i divided 69 and 5 and got 13 4/5 and then i add 69/5 plus 4 and turn the 4 into 4/1 and multiply 1 x 5 and have to do it on the top so 4 x 5 and got 20/5 and now add 69/5 + 20/5 and got 89/5 as my answer and divided 89 divided by 5 and got 17 5/5 and know it that is my answer.
hope it helps you!
Answer:
A) Both estimates are slightly larger, so it is reasonable.
Step-by-step explanation:
Since 1/2 = 5/10
And 1/5 = 8/40
<u>Both estimates are larger</u>
Answer:
1. t<45° 2. d≥200
Step-by-step explanation:
t is less than 45°
it said no less than meaning you can spend 200 or more to get the discount so that means d≥200
Answer:
1.54
Step-by-step explanation:
The cotangent value is referred to as the reciprocal or the opposite of a given tangent value. Cotangent is also referred to as it's short form called cot
Mathematically, Cotangent (cot) = 1/tan
In the above question, we are given a value where:
tan = 33°
Cotangent (cot) = 1/tan 33°
Cotangent (cot) = 1.5398649638
We are told to approximate to the nearest hundredth
= 1.54
<h3><u>The value of x is equal to -6.</u></h3><h3><u>The value of y is equal to 3.</u></h3>
8x + 2y = -42
4x + 7y = -3
In the first equation, subtract 8x from both sides.
2y = -42 - 8x
Divide all terms by 2.
y = -21 - 4x
Now that we have a value of y, we can plug it into the second equation to solve for x.
4x + 7(-21 - 4x) = -3
Distributive property.
4x - 147 - 28x = -3
Combine like terms.
-24x - 147 = -3
Add 147 to both sides.
-24x = 144
Divide both sides by -24.
x = -6
Now that we have a true value for x, we can plug it into either equation to solve for y.
8(-6) + 2y = -42
-48 + 2y = -42
Add 48 to both sides.
2y = 6
Divide both sides by 2.
y = 3
