This one is extremely simple, and we can use the color coded pie chart to find the cost of each of the 5 things.
For the first, decorations, Mary spent $?? as shown by the blue triangle on the pie chart. Let’s get the other ones first to total the money left over.
For the second, she spent $65 on food, as shown by the green triangle on the pie chart.
For the third, she spent $80 on party hall rental, as shown by the blue triangle on the pie chart.
For the fourth, she spent $30 on prizes, as shown by the dark blue triangle.
And for the fifth one, she spent $45 on invitations. A bit too expensive if you ask me.
Then we add all the costs together, and get 220. After adding the extra costs such as candy, costumes, and music, we get a total of $345. We would subtract this from $375 to get a total of $30 left over, which was spent on decorations. The ??? value of the light blue triangle is $30.
Hope this helps!
Answer: y = -4/3x + 15
3y = 45 - 4x (subtract 4x from both sides)
y = -4/3x + 15 (divide both sides by 3)
Answer:
Can u explain more but 0.3 I guess
Step-by-step explanation:
When multiplying exponential expressions 7^a and 7^b, you add up the exponents over the same base of 7. This works because the two bases are both 7
So, 7^a*7^b = 7^(a+b) is the answer
Notes:
1) I used the asterisk symbol instead of the 'x' to mean multiply. This is done so we don't confuse the 'x' with a variable.
2) Parenthesis are needed to indicate that all of the "a+b" is the exponent of 7
