Answer: c. p+n=35, 0.01p+ 0.05n = 1.03
Step-by-step explanation: p= number of pennies, n = number of nickels. Given the total number of coins is 35, we have the equation p+n = 35.
She has total of $1.03. The equation for that would be 0.01p + 0.05n = 1.03
Solve both the equations to get the answer.
Answer:
x=5
Step-by-step explanation:
A^2 + b^2 = c^2
6^2 + 6^2 = c^2
36 + 36 = c^2
72 = c^2
8.5 = c
Answer:
x=2
Step-by-step explanation:
1. AB=AC (The triangle is isosceles. This means that at least two of its sides are equal in length. Looking at the triangle in the picture, sides AB and AC look the same, so we will assume that they are equal. Note that as you get more advanced, assuming isn't the best strategy. <em>You should always try to look for hints if you are ever unsure. For example, if there are two angles that are the same measure in a triangle, the two sides that are only touching one of these angles are equal in length. This is called the </em><em>base angles theorem converse</em><em>.)</em>
2. 9x-3=6x+3 (Rewrite sides AB and AC as the values given in the picture. This is called substitution.)
3. 9x=6x+6 (Add 3 to each side)
4. 3x=6 (Subtract 6x from each side)
5. x=2 (Divide each side by 3)
let me know if i did anything wrong, hope this helps!!
