jessica is thinking of a number that rounds to 1,300 for the nearest hundred. what number might she be thinking of?

1 answer:

4 0

Are there specific options? to round to the nearest hundred, all it needs to be is close to the number rounded (in this case 1,300). the answer could be anywhere from 1,251-1,349. does that make sense?

What is the best first step for solving the given system using substitution while avoiding fractions -9x+4y=10 -9x+3y=3

mylen [45]

Answer:

The best first step for solving the given system using substitution is substitute the value of -9x from equation 1 in equation 2

Step-by-step explanation:

Given : $-9x+4y=10$

$-9x+3y=3$

To Find: What is the best first step for solving the given system using substitution?

Solution:

$-9x+4y=10$ --1

$-9x+3y=3$ --2

Since we are supposed to solve these equations using substitution method

So, the first best step for solving the equation is :

Both the equations contains -9x

So, substitute the value of -9x from equation 1 in equation 2

$10-4y+3y=3$

$10-y=3$

$y=7$

Substitute the value of y in 1 to get value of x

So, $-9x+4(7)=10$

$-9x+28=10$

$9x=18$

$x=2$

Thus the solution is (2,7)

Hence the best first step for solving the given system using substitution is substitute the value of -9x from equation 1 in equation 2

Find hcf of x³y and x⁴y³<br>no a and d

Ierofanga [76]

Answer:

See solutions below

Step-by-step explanation:

a) Given the expressions

x³y and x⁴y³

Find their factors

x³y = (x * x * x * y)

x⁴y³ = (x * x * x * y) * x * y * y

GCF = x*x*x*y

GCF = x³y

The expressions in parenthesis is the GCF. Hence the GCF of x³y and x⁴y³ is x³y

b) For 48m⁶n⁵p⁴ and 20m⁴n⁵p⁶

48m⁶n⁵p⁴ =12 * (4 * m⁴ * n⁵ * p⁴) * m²

20m⁴n⁵p⁶ = 5 * (4 * m⁴ * n⁵ * p⁴) * p²

GCF is the expression common to both terms

GCF = 4 * m⁴ * n⁵ * p⁴

GCF = 4m⁴n⁵p⁴

polet [3.4K]

Answer:

No. if the length is 24 units and the width is 11 units, the perimeter would be p=48+22=70

Step-by-step explanation:

w=11 and l=24

P=2l+2w

P=2(24)+2(11)

P=48+22

P=70
