Answer:
49
Step-by-step explanation:
10-9+8×6÷(5-2^2)
- Solve the <u>parentheses and exponents</u> (5-2^2) 5-4 =1
10-9+8×6÷1
- Solve any <u>multiplication</u> 8×6 =48
10-9+48÷1
- Solve any <u>division</u> 48÷1 =48
10-9+48
- Solve any <u>addition</u> -9+48 =39
10+39
If 6cm=12ft, then if you reduce that you get 1cm=2ft so multiply each measurement by 2 getting 9cm=18ft, 7cm=14ft, 10cm=20ft, 8cm=16ft
Answer:
$1000 ; 500 ; 1000 ; y = 500x + 1000
Step-by-step explanation:
From the graph, the initial deposit which started the savings account is $1000 ; this is the value on the y - intercept, the value in the account at time or period = 0.
The slope :
x1 = 0 ; y1 = 1000
x2 = 6 ; y2 = 4000
Slope = Rise / Run
Rise = y2 - y1 = 4000 - 1000 = 3000
Run = x2 - x1 = 6 - 0 = 6
Hence,
Slope = 3000 / 6
Slope = 500
y - intercept = 1000 (from. Graph)
Equation in slope intercept form:
General form : y = mx + c
m = slope ; c = intercept
Equation is written as ;
y = 500x + 1000
Answer:
x = 12
Step-by-step explanation:
-3x+12=48
-12 -12
*subtract 12 from both sides
-3x = 36
-3x/3 = 36/3
*divide 3 from each sides
x = 12
Answer:
Solution:
the boat's speed in still water: x
The speed with current: (x+3)
The speed against current: (x-3)
The equation is
3(x+3) = 4(x-3)
x = 21 mph
The distance = 3*(21+3)= 72 miles
