Answer:
the number is 105
Step-by-step explanation:
5(x+3) = 3(2x - 1)
5x + 15 = 6x - 3
15 = 1x - 3
(15 + 3)
x = 18
Answer: y=-6x-57
Step-by-step explanation: the normal format of a linear equation is
y=(slope)x+y intercept. The slope is -6 so y=-6x+y intercept. Plugging in the cordinates, -3=-9(-6)+y intercept. We'll call the y intercept b. -3=54+b. Subtract 54 from both sides of the equation and you get b=-54. The linear equation is
y=-6x-57.
You can check by plugging in x= -9, and y= -3. -3=54-57. -3=-3
You have to solve for F so you need to get it by itself which means it would look like:
9/5C+32=F
Then you plug in 33 for C and solve. When you round to the nearest whole number, you get D. 91
1/3x + 2 = 4/3x - 5
2 + 5 = 4/3x - 1/3x
7 = x
y = 1/3(7) + 2
y = 7/3 + 2
y = 7/3 + 6/3
y = 13/3
solution is : (7,13/3) <=
Let us consider,
The problem: 'Find two numbers between which the quotient of 50 ÷ 7 lies'.
Solution: We will solve this in two steps.
Step 1: Form a table of multiples of 7.
Counting number Multiple of 7
1 7
2 14
3 21
4 28
5 35
6 42
7 49
8 56
Step 2: Use the table to find the multiples closest to 50.
Since, 49 = 7 × 7 and 56 = 7 × 8
Thus, 50 lies between 49 and 56.
Then, the quotient is either 7 or 8.
As 50 is closest to 49.
Hence, the quotient of 50 ÷ 7 is 7.
