Which is bigger 6.6 or 0.78 ?
6.6 is bigger

x^2 - xwhen x = 2
2^2 - 2 =
4 - 2 =
2 <==

A = bh
60 = 10h
60/10 = h
6 = hso height is 6 m

900 decreased by 5% =
900 - 0.05(900) = 900 - 45 = 855 <==

2(x + 3) = 8
2x + 6 = 8
2x = 8 - 6
2x = 2
x = 2/2
x = 1 <==

360 in a ratio of 1 to 4

1:4added = 5

1/5(360) = 360/5 = 72
4/5(360) = 1440/5 = 288

ratio is 72:288

3,8,13,16,23this is an arithmetic sequence with a common difference of 5

the nth term : an = a1 + (n - 1)d
an = 3 + 5(n-1) <===

are there decimals in this problembecause the angles of a quadrilateral , when added = 360 degrees

75% = 66what is full cost...
75% of what is 66..
0.75x = 66
x = 66 / 0.75
x = 88 <==

y = 4x - 1...when x = -2
y = 4(-2) - 1
y = -8 - 1
y = -9 <==

6.5 cant see the problem

circumference of circle with radius of 4
C = 2(pi)r
C = 2(3.14)(4)
C = 25.12 cm <== or C = 8*(pi)

6 km / h for 2 hrs 20 min...

6 / 60 = 0.1 km per minute0.1(140) = 14 km <==

to increase an amount by 4.6%, ur multiplier would be 1.046

(x - 5)(x + 4) =
x^2 + 4x - 5x - 20 =
x^2 - x - 20 <===

500 increased by 4.6%
500(1.046) = 523 <==

2x > 7
x > 7/2 or x > 3.5

500 tickets are soldprobability of winning first prize (if there is only 1 first prize) is 1/500dont know how many tickets he bought

6 * 0.6 = 3.6u simply multiply 6 * 6 = 36and since 0.6 has a decimal 1 space to the left, in ur answer(36)...move the decimal 1 space to the left giving u 3.6

5x - 2ywhen x = -2, y = -3
5(-2) - 2(-3) =
-10 + 6 =
-4 <==

0.521 to one significant figure = 0.5

4,7,13,22,34
4 to 7 = 3 spaces
7 to 13 = 5 spaces
13 to 22 = 9 spaces
22 to 34 = 12 spaces
I am sorryI do not know this one..cannot find the pattern

V= bh
V = 3*10
V = 30
not sure about this...because volume of a prism is base * heightthere is o (pi) in the formula.

7.34 * 4.71 = 34.5714 rounds to 34.57
5.63 + 11.89 = 17.52

y = x^2 + 2xx = -2
y = -2^2 + 2(-2)
y = 4 - 4
y = 0 <==
