Answer:
For a polynomial of the form ax2+bx+c a x 2 + b x + c , rewrite the middle term as a sum of two terms whose product is a⋅c=2⋅−2=−4 a ⋅ c = 2 ⋅ - 2 = - 4 and whose sum is b=−3 b = - 3 . Factor −3 - 3 out of −3x - 3 x .
Step-by-step explanation:
We can express an equation to find the fraction of the catering order that is sandwiches or salads by summing up the fractions of the sandwiches and the salads, in this case, the fraction of the sandwiches is 5/12 and the fraction of the salads is 2/12, then the equation looks like this:
c = 5/12 + 2/12, option B is the correct answer
Answer:
<u>10°C average temperature</u>
Step-by-step explanation:
Average Temperature = Lowest + 17
= -7 + 17
= 17 - 7
= <u>10°C average temperature</u>
The unit rate for the graph above is 60 heartbeats per minute. Half of 2 is 1 so go to the 1 min. mark and go up until you reach the line graph and it says 60. Do the same for the 2 min. mark and go up until you reach the line graph and it'll say 120. 60 ÷60=1 and 120 ÷ 60= 2
Answer:
160 total beads
Step-by-step explanation:
so if 1/4 of the beads are red, then 3/4 of them are not.....so 3/4 is the remainder of beads.....and 3/5 of the remainder are yellow....so 3/5 of 3/4 =
3/5 * 3/4 = 9/20...so 9/20 are yellow.....and the rest (48) are blue.
1/4 + 9/20 = 5/20 + 9/20 = 14/20 reduces to 7/10...so 7/10 of the beads are red and yellow
so if 7/10 of the beads are red and yellow, then 3/10 are blue
3/10 of what number is 48
3/10x = 48
x = 48 * 10/3
x = 480/3
x = 160
let me check it..
1/4 are red......160 total beads.....so red beads = (1/4 * 160) = 160/4 = 40
3/5 of the remainder is yellow.....so 3/5 of (160 - 40) = 3/5(120) = 72 yellow
and then u have 48 blue...
40 + 72 + 48 = 160
so there are 160 total beads.......40 red, 72 yellow, and 48 blue <===
