I believe it is C. Multiply 640 by 7.5. You should get 4800
First you should write what you know since we don't know how many helmets we will use x
helmets - 5(x)
bats - 3(6x)
then write out the equation
5(x)+3(6x)=4600
then solve so first multiple 5 times x and multiply 3 and 6x
5x+18x=4600
then combine like terms which are 5x and 18x
23x=4600
then divide both sides by 23
x=200
200is the number of helmets and since there are six times the bats as helmets you multiply that by six and get
helmets=200
bats=1200
if x is a regular cip of coffee and y is a large cup of coffee. the first part of the equation being the number of the cups of coffee and the second part expressing the price. using the method of substitution we solve for x in the first equation
x= 5-y
and then we solve for y
then we substitute the value found in the easiest equation which would be the first one and we solve for x
x + 2 = 5
x + 2 - 2 = 5 - 2
x = 3
so its 3 regular cups and 2 large
Answer:
Answer = x^5 + 5x^4 + 10x^3 + 10x^2 + 5x + 1
Step-by-step explanation:
Look at image
it's a lot of solution
i hope this helps
Good luck
