Answer:
B.
Step-by-step explanation:
1.6d=30
2. Start with dividing each side by 6 since its the only number which will leave the variable d by itself and the other side of the equal sign with 5
3. Which will leave the answer with d=5
Answer:
x = 2 and y = 5
Step-by-step explanation:
Given the simultaneous linear equations
y = 2x + 1 and x + y = 7
We are to find the value of x and y;
Substitute 1 into 2
From 2;
x+y = 7
x+2x+1 = 7
3x+1 = 7
3x = 7-1
3x = 6
x = 6/3
x = 2
Recall that y = 2x+1
y = 2(2) + 1
y = 4+1
y = 5
Hence the solution from the graph will be the point where the line cuts the x axis and this will be at x = 2 and y = 5
Answer:
There’s no image, but to find the perimeter of the triangle just add up the totals of each side.
Step-by-step explanation:
To multiply exponents with like bases, simply add the exponents...
3^-3 × 3^4 × 3 × 3^-5 =
add exponents across, remember just 3 means 3^1.
-3 + 4 + 1 + -5 = -3
answer is 3^-3
Answer:
21.25
Step-by-step explanation:
you would multiply 25 by 0.15 to get the percent being taken off then subtract that from your original price
