Answer and explanation:
- 5 = b - 2.3 add 2.3 to both sides
+2.3 +2.3
- 2.7 = b
Answer:
red=28℅,yellow =20℅, purple =16℅, green =12℅, orange=24℅
Step-by-step explanation:
total skittles =125
now,
To find the percentage of each skittles,
red =35 (<u>3</u><u>5</u><u> </u>×100) =28 ℅
125
u can find each ℅ by same method.
hope it help u.
Given that f(x) = ax – 5 and f(4) = 15, then the value of a is 5
The given function is:
f(x) = ax - 5
If f(4) = 15, then x = 4
Substitute x = 4 into f(x) = ax - 5
f(4) = a(4) - 5
15 = 4a - 5
Solve for a by adding 5 to both sides
15 + 5 = 4a - 5 + 5
20 = 4a
Divide both sides by 4
4a/4 = 20/4
a = 5
Given that f(x) = ax – 5 and f(4) = 15, then the value of a is 5

Answer:
3/4
Step-by-step explanation:
To find the slope using a line on a graph, calculate the difference between two points. To do so, use the formula y2 - y1/x2 - x1.
Two points on this line are (0, -1) and (4, 2). This means:
y2 = 2
y1 = -1
x2 = 4
x1 = 0
Plugging those values in, we get:
2 - (-1)/4 - 0
Evaluating 2 - (-1) and 4 - 0, we get 3/4. Therefore, the slope is 3/4.
