Answer:
7b = 10
Step-by-step explanation:
We have that:
5a + 2b = 0
a is two less than b
So a = b - 2.
Replacing in the above equation:
7b
7b = 10
Answer:
y = 40x
Step-by-step explanation:
Given - Alex walks from her home to the bus stop at a rate of 40 steps per minute.
To find - Write a rule they gives her from home in steps as a function of time after she leaves her home.
Proof -
The function will be a linear function.
The linear function is in the format of y(x) = mx + c
Let x be the total minutes
y be the total steps
So, the rule becomes
y(x) = 40x + 0
⇒y = 40x
As she walks 40 steps in 1 minutes
So, rate of change will be 40 and constant term will be 0.
Answer:
The total number of cubes in each shape will alternate between even and odd.
The length of each shape will alternate between even numbers and odd numbers
Step-by-step explanation:
I have drawn a picture of the cubes below.
The cubes for Step 1 are black.
Those added in Step 2 are pink.
Each step has cubes of a different colour.
The total number of cubes in each shape (Column 4 in the table) alternates between even and odd.
The length of each shape (Column 3 in the table) alternates between even and odd.
Answer:this is quite hard as i cant see the cone but the one you have may be the answer i am not sure of this beacuse i cannot see the cone shape.

Answer:
Possible numbers for Joshua's house are #13 and #21.
Step-by-step explanation:
Given:
Vacation houses are equally spaced along a street.
The first house is marked with #10 and so on.
Maria lives in house marked as #17.
Joshua lives 4 houses away from Maria.
So, the difference between Joshua's house number and Maria's house number is 4.
Let 'x' be the house number of Joshua's house.
Case 1: If Joshua's house is after Maria's house. So,
Case 2: If Joshua's house is before Maria's house. So,
Therefore, the possible numbers for Joshua's house are #13 and #21.
