Answer:
50,27
Step-by-step explanation:
let the parts be x and y
x+y=77
x=2y-4
substitute
2y-4+y=77
3y=77+4
3y=81
y=81/3=27
x=2×27-4=54-4=50
During a walk on a trail, Rose walked a total of 3,674 steps. Assume that she takes the same number of steps each time she
walks this same trail and that she walks this same trail 11 times. Estimate the number of steps Rose would take after all 11
walks.
Round each walk to the nearest hundred steps before calculating.
Answer:
40,790 steps
Step-by-step explanation:
3674 rounds to 3700
3700*11 = 3700*10+3700*1 = 37000+3700 = 40,790
Answer:
Step-by-step explanation:
3.674 is rounded to 3,700 steps every 11 walks.
3,700 x 11 Walks= 40, 700
Find the length of the third side of the right triangle. Give an exact answer and an approximation to three decimal places if needed.
Answer:
a = 32
Step-by-step explanation:
This is a right triangle and the square value of hypotenuse is equal to sum of square value of other two side lengths
68^2 = 60^2 + a^2
4624 = 3600 + a^2
4624 - 3600 = a^2
1024 = a^2 find the root for both sides
32 = a

WILL MARK BRAINLIEST !!! HELP !
the triangles below are similar use what you know about similar triangles to find the missing side length
is the expression 5+3x/2 equal to the expression 4x
Answer:
No
Step-by-step explanation:
[5+3x] is an expression that cannot be added because 5 is a natural interger but 3x is an unknown
and therefore it cannot be divided by 2 to get 4
Better example :
if the question will give 4x , then
it should be [5x+3x]/2 = 8x/2 = 4x
it's obvious from the example I gave that 8x can be divided by 2 to give 4x
4 1/2 ÷(−1 3/7 ) please help and hurry
Hi! I'm happy to help!
To first solve this, we need to make those mixed numbers improper fractions.
To make 4 1/2 an improper fraction, you have to turn 4 into halves (multiply four by 2) then add the extra half, giving you 9/2.
[tex]\frac{9}{2}[/tex] ÷(−1[tex]\frac{3}{7}[/tex] )
Now, we turn 1 3/7 into an improper fraction. We turn 1 into sevenths (multiply 1 by 7) then add the other 3 sevenths, giving you 10/7.
[tex]\frac{9}{2}[/tex] ÷(−[tex]\frac{10}{7}[/tex] )
From here, we need to turn this problem into a multiplication problem in order to solve. Since multiplication is the opposite of division, we need to get the opposite of something, so we use our second fraction and flip it.
[tex]\frac{9}{2}[/tex] ×(−[tex]\frac{7}{10}[/tex] )
Now, we multiply the top by the top, and the bottom by the bottom. (any positive multiplied by a negative gives a negative)
-[tex]\frac{63}{20}[/tex]
Since we cannot simplify, our final answer is -63/20.

what is 20% of 35
Answer:
7
Step-by-step explanation:
2(5x-4)-x-3(3x-1)
simplified
Answer:
x=-5
Step-by-step explanation:
2(5x-4)=10x-8
-3(3x-1)=-9x+3
10x-8-9x+3
x=-5
The answer you are looking for is -5.
Writing out the equation,
2(5x-4)-x-3(3x-1)
Using the Distributive Property for 2(5x-4) and -3(3x-1),
10x-8-x-9x+3
Using the Associative Property,
10x-x-9x-8+3
Simplifying the similar terms,
9x-9x-8+3
Canceling both "9x" terms, since 9x-9x is obviously 0,
0-8+3, or simply just -8+3.
-8+3=-5
So, therefore the final answer is -5.
I hope that this has helped you. Enjoy your day, and take care.

the ratio of 3 less than k to 2 more than k
We will find that the ratio of 3 less than k to 2 more than k is:
(k - 3):(k + 2)
The ratio between two numbers A and B can be written as:
A:B
This is the ratio of A to B
and
B:A
Is the ratio of B to A.
Then for the ratio of 3 less than k to 2 more than k we have:
"3 less than k" is: k - 3
"2 more than k" is: k+ 2
Then the ratio is:
(k - 3):(k + 2)

15 = [tex]\frac{5}{3}[/tex] (x + 12)
Answer:
x = -3
Step-by-step explanation:
15 = 5/3 (x + 12)
Multiply each side by 3/5 to clear the fraction
3/5 *15 =3/5 *5/3 (x + 12)
9 = x+12
Subtract 12 from each side
9-12 = x+12-12
-3 =x
Answer:
15 = 5/3(x + 12)
Using distributive law
15 = 5x/3 + 20
15 = 5x + 60/3
15 × 3 = 5x + 60
45 = 5x + 60
45 - 60 = 5x
-15 = 5x
-15/5 = x
-3 = x
