If x = 9 and y = -2 what’s 10 + 5xy

Answers

Answer:

10 + 5xy = -80

Step-by-step explanation:

10 + 5xy = ?

x = 9 and y = -2

10 + 5xy = 10 + 5(9)(-2)

             = 10 - 90

             = -80

Answers

(10*4+2)(9+6 / 3)         (first do the mutiplication and division)

(40+2)(9+2)               (add)

(42)(11)                        (multiply)

42 *11

462 \ \textless \ -answer
first you multiply 10 and 4 because multiplication before addition and you get 40 then you add 40 and 2 to get 42 now you move to the second equation and you divide 6 and 8 because division comes before addition and you get 2 when you divide 6 and 3 now you add 9 and 2 and get 11 now you multiply  42 and 11 (because the parenthesis have nothing between them it means multiplication) and you get 462 as your answer

X^a+bm
3rd answer
Parenthesis means b x m
a is not right next to b so you add that to b x m
x^a(x^b)^m = x^(a+bm)

When multiplying numbers, the base (x) must be the same.  Add the exponents.  When raising (x^b)^m, multiply exponents.

Examples:  x²x³ = x^5.
x²(x³)² = x²x³x³ = x^8  [2x(3x2)]

In the second equation, division of exponents means to subtract.  The big clue is 8/4 = 2, so any correct answer must be preceded by 2.

5-4 = 1, and x^1 = x.  So:  2x

Estimate the sum for 1,537 times 242 then find the sum

Answers

Answer: Two values are 369600 and 300000.

Step-by-step explanation:

If we rounding the integers to nearest  ones ,

1537 \text{change into }1540\n\n242\text{ change into }240\n\nSo,\n\text{Sum will be }\n=1540* 240\n=369600

If we rounding the integers to nearest tens,

1537\text{ changes to }1500\n242\text{ changes to }200\nSo,\n\text{Sum will be }\n=1500* 200\n=300000

Hence, by estimation, we get

Two values from above two cases are 369600 and 300000.

Final answer:

The estimated product of 1,537 and 242 is 300,000. The exact product is 372,094.

Explanation:

The question is asking to first estimate and then find the exact product of 1,537 and 242. To estimate, we could round 1,537 to 1,500 and 242 to 200 and then multiply those round numbers. This gives us an estimate of 300,000.

For the exact calculation, we have to multiply 1,537 by 242 which equals 372,094.  So, the exact product of 1,537 and 242 is 372,094.
