Answer:
Step-by-step explanation:
Givens
4 scones
1 loaf of bread
Total cost = 3.30
Equation
Let the loaf of bread = b
Let the scones = s
Cost = b + 4s
Solution
Substitute the givens into the equation
b + 4s = Cost
90 + 4s = 3.30 Subtract 90 from both sides
90-90 + 4s = 3.30-90 Combine
4s = 2.40 Divide by 4
4s/4 = 2.40/4
s = 0.6 of a pound
Answer: 1 scone = <u>60 pence</u>.
Answer:
1 mile =1609 km
Step-by-step explanation:
Answer: y=4x-10
Step 1: Write model equation
The model equation for slope- intercept form is y=mx+b
M-Slope
X-Variable
B- Y-intercept
Step 2: Slope
Since we know that m is slope, we can substitute the slope given (1/4) into the equation
y=mx+b
y=4x+b
Step 3: Y-intercept
The final thing we have to do is solve for the y-intercept, or b. We’ll do this by substituting the point into the equation and solving.
y=4x+b
*substitute point*
6=4(4)+b
*multiply 4 and 4*
6=16+b
*subtract 16 on both sides*
-10=b
Step 4: Check your answer
We will check our answer by substituting all the values into the equation and seeing if the left and right side equal each other
y=mx +b
6=4(4)-10
6=16-10
6=6
This is correct! Hope this helps comment below for more questions :)
