UGH! RSM!!!!!!!!!!!!!!!!!!!!! John's family visited his grandmother over the weekend. The drive to her house took 2 hours at their usual speed. the trip home took 15 minutes longer because traffic was bad and they had to drive 5 mph slower. How many miles away is john's grandmother's house? will give BRAINLIEST! +10pts!
Answers
Hope this helps!
Answer:
90 miles!
Step-by-step explanation:
there are two parts to the problem, meaning you'll need 2 equations.
let's call the distance TO the grandma's house d1, and BACK from the grandma's house d2.
KEY:
time TO g'ma house= t1
time FROM g'ma house=t2
(replace the t's with 's' for speed, with the '1' for to, and '2' for from)
(distance is a constant so d1 is always equal to d2).
-------------
d1=s1+t1, d2=s2+t2
we know what t1 is. 2 hours.
d1=s1•2
meaning that d2 is also equal to that.
s1•2=(s1-5)•2 1/4
2s1=2 1/4 s1-11 1/4
11 1/4= 2 1/4 s1-2s1
11 1/4 = 1/4 s1
s1 (to g'ma)=45 mph
distance is speed times time.
so 45•2 (hr) = 90.

40 = 8y
there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.

Write a system of equations.
Answers
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

The diagonal of a TV is 42 inches. The base is 38 inches wide. How tall is the Tv? Round your answer to the nearest tenth. Put your answer in the box. EX: 10
Answers
Answer:20.6 inches
Step-by-step explanation:
The diagonal measure of a rectangular TV screen is 42 inches. The width of the screen is 36.6 inches.
The diagonal , width and height forms a right angle triangle
So we apply pythagorean theorem
Diagonal is the hypotenuse
LEt the height of the screen is 'h'
c^2= a^2 + b^2
42^2= 36.6^2 + h^2
Subtract 36.6^2 from both sides
h^2 = 424.44
Take square root on both sides
h=20.60194
Round to nearest tenth
Height of the screen = 20.6 inches
Answer:
1,600 inches
Step-by-step explanation:
You need to take the height of the tv and the base of the tv. So you need to take 42x38= 1,596. Now you need to round to the nearest tenth. So take 1,596 and the nearest tenth would be 1,600. Because 1,596 is closer to 1,596 then 1,590.

x = 6
Step-by-step explanation:
10 - 4 = 6
The x means the number is unkown, well, we know that 6+4=10, so there you go!
Answer:
6
Step-by-step explanation:
x is a mystery number. We don't know what it is, but we know that if you add 4 to it, we get 10. To what number should we add 4 to get 10?
That's right, 6.
A more advanced explanation:
We need to isolate x, so it will be alone on one side of the equation. To do this, we must subtract 4 from the left side of the equation, so it will be x + 0, or x. But we also need to remember that equations always need to be balanced, so we need to subtract 4 from both sides, to get x + 0 = 10 - 4. Simplifying, we get that x = 6.
