Write an expression

A. Sum of 66, k, and 10
B. Y squared
C. Sum of s and 49
D. Sum of 58, c, and 100
E. Product of 62 and x
F. Difference of 29 and v
G. 7 divided by k
H. Sum of w and 3
I. T times 45
J. C times 3
K. W added to 9
L. 93 divided by y

Solve the equations

A. 3.6(t+4.6) =4
B. 2.6=6(c-3.7)
C. 4(-1.8-p) =-2.4
D. 8(z-3.1) +6=3z+5

Step-by-step explanation:

Step 1:  Solve the first part

A: 66 + k + 10

B:  y^2

C: s + 49

D:  58 +c + 100

E: 62 * x

F: 29 - v

G:  7 / k  

H: w + 3

I: t * 45

J:  c * 3

K:  9 + w

L:  93 / y

Step 2:  Solve the second part

A:  (3.6 * t) + (3.6 * 4.6) = 4

    3.6t + 16.56 - 16.56 = 4 - 16.56

    3.6t / 3.6 = -12.56 / 3.6

    t = -3.4888...

B: 2.6 = (6 * c) + (6 * -3.7)

     2.6 + 22.2 = 6c - 22.2 + 22.2

     24.8 / 6 = 6c / 6

     4.1333... = c

C: (4 * -1.8) + (4 * -p) = -2.4

    -7.2 - 4p + 7.2 = -2.4 + 7.2

    -4p / -4 = 4.8 / -4

     p = -1.2

D: (8 * z) + (8 * -3.1) + 6 = 3z + 5

       8z - 24.8 + 6 - 3z = 3z + 5 - 3z

5z - 18.8 + 18.8 = 5 + 18.8

5z / 5 = 23.8 / 5

z = 4.76

answer: ♡♡♡♡♡♡♡♡♡♡

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
