Answer:1,200 students
Step-by-step explanation:
540/45=12=1%
12*100=1,200
Answer:
if the prices at the bottom are per pound, then:
pears = 3.7604 (3.76)
apples = 1.1385 (1.13)
peaches = 2.8122 (2.81)
total bill = 7.07
Step-by-step explanation:
pears =
1.19 x 3.16 = 3.7604 (3.76)
apples =
0.99 x 1.15 = 1.1385 (1.13)
peaches =
1.29 x 2.18 = 2.8122 (2.81)
total bill =
3.76 + 1.13 + 2.81 = x
x = 7.7
7.7 money-wise = 7.07 <em><u>(i think)</u></em>
total bill = 7.07
OR
total bill =
3.7604 + 1.1385 + 2.8122 = x
x = 7.7111
----------------
7.7111 = 7.7 = 7.07
Could be anything depending on what a is. I imagine for the question it is just supposed to be simplified to 4a + 2
Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
11/7 = x/13
x = 13*11/7 ≈ 20.4 ← <span>to the nearest tenth</span>
