Answer:
3x+19
Step-by-step explanation:
2x are like terms and 4 and 15 are like terms so you add them together
Answer: Raju travels at a higher speed.
Step-by-step explanation:
Speed inversely proportional to time.
As time taken to cover a particular distance decreases the speed will increase.
Raju covers a certain distance in 1 hour.
Sham covers the same distance in 2 hours.
1< 2
Thus Raju travels at a higher speed.
I think it would be 10x+y because the slope is the amount he spends each month for the streaming service so then it would be 10x because x represent the number of months and then it’s +y because that’s the amount he already spent on the tablet
Answer:
- n = 5q; 25q+5n = 200
- (n, q) = (20, 4)
- Margie has 20 nickels and 4 quarters
Step-by-step explanation:
a) Using the defined variables, we can translate the problem statements to equations:
- n = 5q . . . . Margie has 5 times as many nickels as quarters
- 25q + 5n = 200 . . . . the total value of Margie's coins is 200 cents
__
b) Substituting for n, we have ...
25q +5(5q) = 200
50q = 200 . . . . . . . collect terms
q = 200/50 = 4 . . . divide by the coefficient of q
n = 5·4 = 20
The solution is (n, q) = (20, 4).
__
c) Since n represents the number of nickels Margie has, n=20 means Margie has 20 nickels. Similarly, q=4 means Margie has 4 quarters.
Answer:
The perimeter is 44cm.
Step-by-step explanation:
The perimeter is the length of all the sides. So, to calculate the perimeter, add all the sides together.
However, there are two sides that do not have a measure written. So we must first calculate them:
The long vertical side can be calculated by subtracting the other vertical sides by the long bottom side:
14 - 5 - 6 = 3cm
The missing horizontal side can be found by subtracting the leftmost side by the shorter horizontal sides:
8 - 3 - 2 = 3cm
Now, add them all together:
8cm + 5cm + 3cm + 3cm + 3cm + 6cm + 2cm + 14cm = 44cm
