Answer:
AEB =305° as stated below
Step-by-step explanation:
AEB is the larger area starting A to EB and missing out the small AB area
EC = 180° = supplementary we label 87° angle to P.
P+ BCD = 87, + 38 = 125°
ABCD = 180°
180 - BCD = 180-125°
AB = 55°
Therefore AEB = 360-55=305°
Answer:
(x+7)÷5
Step-by-step explanation:
since the number is unknown, it becomes X. Because we first add 7 then divide by 5, the expression will be a bracketed (X+7), followed by the division by 5. This makes sense because of the BODMAS rule to which, in coherence with the BODMAS rule, we first solve the expression in the brackets then move on outside them.
A=4 because √a=-2 the you square each side to make it a=4.
Answer: Choice C
The first inequality is 
The second inequality is 
Replace x with whatever letter your teacher is using
=========================================================
Let x be the number of cans collected on week 3
Add this to the previous totals (for weeks 1 and 2) to get 124 + 121 + x. I'm going to leave this as is and not simplify. This is so the answer matches up. This total must be greater than or equal to 400, meaning 124+121+x can be 400 or larger.
124+121+x >= 400
245+x >= 400 .... combine like terms
x >= 400-245 .... subtract 245 from both sides
x >= 155
So you need to collect at least 155 cans for the third week so that you'll have at least 400 cans total.
