1. Simplify the expression:<br> 4+36+(10-8)’-3+7<br> A. 130<br> B. 100<br> C. 38<br> D. 37
Alika [10]

Answer:

The answer isn't in the options anyway I'll write it. the answer is 46.

Step-by-step explanation:

According to BODMAS rule - addition should be done first so

4+36= 40 and -3 +7 = 4 so 40+4 ,= 44

then we should do subtracting so, 10-8 = 2

to conclude we should bring the equation to an end so,

44+2 = 46

HOPE THIS HELPS YOU

Linear equation topic. (Lisa is 5 years younger than his elder brother,Daniel.The product of their ages is 2/3 of their grandmot
alisha [4.7K]
Let Daniel's age be 'x' years , hence, Lisa's age is (x - 5) years. Let Grandma's age be 'y' = 54 years.
Hence,
x(x - 5) = 2/3 × y
x² - 5x = 2 × 54 years / 3
x² - 5x = 36 years
x² - 5x - 36 = 0
∆ = (-5)² - 4(1)(-36) = 25 + 144 = 169
√∆ = √169 = 13
x\:  =  \:  \frac{ - b \:   \frac{ + }{ }   \:  \sqrt{ {b}^{2}  \:  -  \: 4ac} }{2a}
x1 = (5+13)/2, x2 = (5-13)/2
x1 = 9, x2 = -4
Since, age can't be negative,
Daniel's age = x = 9 years.

they hold an anual pass that cost $40.00. each canoe rental costs $26.00 and each bicycle rental cost $15.00. use an algebraic e
postnew [5]

Answer:

Cost = 40.00 + 26.00c + 15.00b

Step-by-step explanation:

Let c = number of canoe rentals

and b = number of bicycle rentals. Then

   Annual pass = 40.00

Canoe rentals = 26.00c

Bicycle rentals = 15.00b

        Total cost = 40.00 + 26.00c + 15.00b

Equation Practice with vertical angles <br><br><br>Please solve for x
Harrizon [31]

Answer:

x=20

Step-by-step explanation:

These angles are vertical angles so they are equal.

7x-99 = 2x+1

Subtract 2x from each side

7x-2x -99 = 2x-2x+1

5x -99 =1

Add 99 to each side

5x-99+99 = 1+99

5x = 100

Divide each side by 5

5x/5 =100/5

x = 20
