Answer:
He travelled 99 miles and has 351 miles to travel
Step-by-step explanation:
Here,
22/100×450
=22/2×9
=11×9
=99 miles travelled
Again,
450 miles - 99 miles
= 351 miles left to travel
(would appreciate it if you could mark me the brainliest :))
Answer:
3.5
Step-by-step explanation:
2(5x-9)=17
10x-18=17
+18
10x=35
÷10
x=3.5
or
2(5x-9)=17
÷2
5x-9=8.5
+9
5x=17.5
÷5
x=3.5
Answer:
38 miles per gallon
Step-by-step explanation:
465 miles / 12 gallons
38 miles / gallon
It could be a proportion
24:36=42:x
make into fractions
24/36=42/x
2/3=42/x
multiply both sides by 3x
2x=126
divid oth sides by 2
x=63
the other number is 63
24:36=42:63
Answer:
y = -(2/3)x + 3
C
Step-by-step explanation:
The slope of the equation that was given is - 2/3
The slope in a slope intercept equation is the number in front of the x when the value of the number in front of the y = 1 and x and y are on opposite sides of the equal sign. Let's translate that.
The original equation is y = -(2/3)x + 5/3
- y and x have to be on opposite sides of the equal sign [They are]
- The slope is the number in front of the x. That's (-2/3). That makes A incorrect.
Now you need to use the given point
The point is (-3 , 5) Put this into the equation that you have so far
y = (-2/3)x + b
y = 5
x = -3
5 = (-2/3)(-3/1) + b Substitute in the givens
5 = (-2 * -3)/3 + b Multiply -2 * - 3 = 6
5 = 6/3 + b Divide the 6 by 3
5 = 2 + b Divide
5 - 2 = b Subtract 2 from both sides
3 = b Switch sides
b = 3
Answer y = (-2/3)x + 3 or C
