-2(4x-1)-7=5
whats the next step in solving this equation
Answer:
Using distributive property is the next step in solving the equation
Step-by-step explanation:
-2(4x-1)-7=5
-8x+2-7=5
Answer:
The next step would be to do distributive property.
Step-by-step explanation:
-2(4x-1)-7=5
-8x + 2 - 7 = 5
-8x - 5 = 5
+5 +5
-8x = 10
/-8 /-8
x= -5/4
or
x = -1 1/4
Hope this helps and I hope u have an Amazing day!!
If you add Natalie's age and Fred's age, the result is 46. If you add Fred's age to 4 times Natalie's age, the result is 91. Write and solve a system of equations to find how old Fred and Natalie are.
Answer:
Fred = 31
Natalie = 15
Step-by-step explanation:
We have Natalie and Fred's whos age are unknown, we know that when added, their ages equal 46. While when multiplied with Natalie's age 4 times, their ages is 91.
Create two systems :
F = Fred
N = Natalie
F + N = 46
4N + F = 91
We can change the first equation to Natalie's age alone :
N = 46 - F
Now substitute this into the second equation :
4(46 - F) + F = 91
Distribute :
184 - 4F + F = 91
Subtract 184 from both sides :
-4F + F = -93
Add like terms :
-3F = -93
Divide -3 from both sides :
F = 31
Therefore, Fred is 31 years old. Now replace his age in the first equation :
31 + N = 46
46 - 31
15
Therefore, Natalie is 15 years old.
-2j - 10 = -6 She calculated j = 8
Is this correct or incorrect?
Answer:
incorrect
Step-by-step explanation:
this is incorrect because i solved it and i didn't got that answer
hope this helps:)
Pls mark brainlist
Answer:
Incorrectj = -2Explanation:
-2j - 10 = -6
Add 10 To Both Sides−2j − 10 + 10 = −6 + 10
−2j = 4
Divide Both Sides By -2-2j / -2 = 4 / -2
j = -2Answer fast!!!!!!!!!!!!!!
can someone help me find the equation for this line please
Answer:
y = x + 1
Step-by-step explanation:
The line y = x goes through the origin, and forms a perfect 45 degree angle with the x axis.
This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.
Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so
y = 1x + 1 = x + 1
y = x + 1

You roll 2 fair 6-sided dice. What is the probability of rolling a sum of 7 or more?
18/36 or 1/2
20/36 or 5/9
19/39
21/36 or 7/12
Answer:
here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.
Now, it is time to calculate the probability.
The required probability is,
p = (No. of cases favorable for the event)/(Total no. of cases)
=6/36 =
Step-by-step explanation:
Two fair six-sided dice are rolled. What is the probability that the sum of the two dice is seven?

ABCD is a trapezium
AD=10cm
AB=9cm
DC=3cm
Angle ABC=angled BCD=90degrees
Calculate the length of AC
Give your answer correct to 3 significant figures
Answer:
12.0 cm
Step-by-step explanation:
✔️First, find the height, BC, of the trapezium using Pythagorean Theorem.
BC² = 10² - (9 -3)²
BC² = 10² - 6²
BC² = 64
BC = √64
BC = 8 cm
✔️Find AC using Pythagorean Theorem:
AC² = AB² + BC²
AC² = 9² + 8²
AC² = 145
AC = √145
AC = 12.0415946 ≈ 12.0 (3 significant figures)
y'all I need help asap
Answer:
Let's solve for x.
4x+5y=7
Step 1: Add -5y to both sides.
4x+5y+−5y=7+−5y
4x=−5y+7
Step 2: Divide both sides by 4.
4x/4=−5y+7/4
x=−5/4 y+ 7/4
Answer: for the first one x=−5/4 y+ 7/4
3x−2y=−12
Step 1: Add 2y to both sides.
3x−2y+2y=−12+2y
3x=2y−12
Step 2: Divide both sides by 3.
3x/3=2y−12/3
x=2/3y−4
Answer:
x=2/3y−4

how to evaluate higher powers of i
Answer:
i^0 = 1
i^1 = i
i^2 = -1
i^3 = -i
i^4 = 1
i^5 = i
i^6 = -1
i^7 = -i
i^8 = 1
i^9 = i
Step-by-step explanation:
Anything raised to 0 is 1
Anything raised to 1 is itself
I just always knew i^2 = -1
I put this rest into the calculator honestly
But if you look at the stuff from i^2, you'll notice there's a pattern (-1, -i, 1, i) and it repeats. I bet if you raise i to the 10th, 11th, 12th, and 13th power, it is going to repeat the same pattern. I hope this helps in any way.
