Answer:
Step-by-step explanation:
Let's replace Ram with r and Sudha with s.
(r = 3s) + 3 = (r = 2s)
(r = 2x) = ( r = 3s - 3)
3s - 3 = 2x
3s - 1x = 2x
s = 3
If r = 3s and s = 3, then r = 3 x 3 = 9.
Ram is 9 years old and Sudha is 3 years old.
Answer:
age of ram = 9 years
and the age of sudha is 3 years
Step-by-step explanation:
let the present age of ram be x
and his sister sudha's present age be y
Ram is three times as old as his sister Sudha
so, x = 3y ----i)
After three years, he will be twice as old as Sudha.
so , x+3 =(y+3)2
=> x+3 = 2y+6 ----ii)
now putting the value of x in equation ii)
=> 3y+3 = 2y+6
=> 3y-2y = 6-3
=> y = 3 { the present age of sudha is 3 year}
now the age of ram = x = 3y
=> x = 3(3)
=> x = 9
Over the last three evenings, Diane received a total of 105 phone calls at the call center. The third evening, she received 4 times as many calls as the second evening. The first evening, she received 9 fewer calls than the second evening. How many phone calls did she receive each evening?'
Answer:
Make an eqaution from here.
Let’s make evening 2 “x”
So the first evening has 9 less then the secon evening so…
x-9
Of course theres the second evening (x).
X-9+x
Then the third evening has 4 times as much as the second meeting so…
x-9+x+4x
And when solved, it has to equal 105.
So solve from here.
Combine like terms.
6x-9=105
Isolate
6x=114
x= 19
First evening is 9 less then 19, so 10.
The second evening was 19 calls.
The third evening was 4 times the second evening so, 19*4= 76
1st night = 10
2nd night= 19 calls
Thrid night= 76 calls
Simplify the expression.
2.5-5.5n - 3n + 6
simplified, it should be -8.5n+8.5
What is the value of x ? ( x= ??)
A x = 121
B x = 10
C x - 59
D x = 20
Answer:
The variable x is equal to 10 degrees.
Step-by-step explanation:
A triangle's angles, in total, must equal 180 degrees.
71 + 50 + (6x-1) = 180
71 +50 = 121
121 + (6x-1) = 180
6x - 1 = 59
6x = 60
x = 10

? = 9%
112 = 100% 18x112 /100 =. 20.16$

Is g = 4 a solution to the inequality below? 8 − g > 4
Answer:
Given, 3x−2<2x+1
⇒3x−2x<1+2
⇒x<3orx∈(−∞,3)
The lines y=3x−2 and y=2x+1 both will intersect at x=3
Clearly, the dark line shows the solution of 3x−2<2x+1.
Answer:
No
Step-by-step explanation:
If you input g = 4 into the inequality, you have
8 - 4 > 4
4 > 4
4 is NOT greater than 4
To be correct, the inequality would have to read:
8 - g ≥ 4
This would be correct because now it reads
4 ≥ 4
4 is greater than OR equal to four

A flagpole is 45 feet tall. A rope is tied to the top of the flag pole and secured to the ground 10 feet from the base of the flagpole. Will a 35 foot piece of rope be long enough to secure the flagpole? Justify your answer.
i give brainliest
Answer:
So the answer would be no, because the length of the rope is needs to be 46 and 35 is not long enough
Step-by-step explanation:
A flagpole, rope and the length of secure point from the flagpole are forming the right triangle, where the rope is a hypotenuse. Let a = 45 and b = 10ft. Use Pythagorean Formula to find length of the rope c
a² + b² = c²
Since we are going to solve for c, we set up the equation like this:
c² = 45² + 10² (Substitute into formula)
c² = 2,025 + 100 (Add)
c² = 2,125 (Simplify)
√c² = √2,125 (Take the square root from both sides)
c = 46.09772228646444 (Round to the nearest whole number)
c = 46
So the answer would be no, since the length of the rope needs to be 46ft long and a 35 foot piece of rope is not long enough.
Is (-5,2) a solution to this system of equations?
x=-5
y=2x+10
Answer: No, it's not the solution
Explanation:
Let's plug x = -5 into the second equation
y = 2x+10
y = 2(-5)+10
y = -10+10
y = 0
This shows that (-5,0) is the actual solution, instead of (-5,2)

Answer:
4/15
Step-by-step explanation:
They have baked 1/3 + 2/5. To add you need common denominators.
1/3 = 5/15, 2/5 = 6/15
5/15 + 6/15 = 11/15. This is what they baked.
To find what is left, we need to subtract from 1. 1 = 15/15
15/15 - 11/15 = 4/15

James and Sarah went out to lunch. The price of lunch for both of them was $80. They tipped their server 20% of that amount. How much did each person pay if they shared the price of lunch and the tip equally? Each person paid $
Answer:
28 Dollars
Step-by-step explanation:
80 diveded by 2 is 40
20 percent of 40 is 8
there for each should have tipped 28
Answer:
total tipped = 20% × $80
= $16
total lunch price = $80 - $16
= $64
amount each person pay for tipped
= $16 ÷ 2
= $8
amount each person pay for lunch
= $64 ÷ 2
= $32
total each person pay for lunch and tipped
= $8 + $32
= $40
