Row 4 = Kilogram (Larger unit)

Row 5 = Thousand (Larger Unit)

Row 6 = Micrometer (Larger Unit)

Row 7 = 100,000 (How many times as large as)

Answer:

x=y-44 and x+y=410

Step-by-step explanation:

So, you want to use the equations x=y-44 and  x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point  (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.

Answer:

9 bags

Step-by-step explanation:

Weight each bag should be = 3/4 pound (0.75 pound)

Total weight of sunflower seeds available = 6.5 pounds

Number of packages made = 6.5/ 3/4

                                              = 8.66666666667

                                              = So 9 bags at the most

If you write 8, then  you wouldn't  be able to fit the other 0.5 pound and if you put 9, well you will have enough more space to put 6.5 pounds.

A, the solutions are x=3,2

Step-by-step explanation:

A complex number is said to be additive if  the sum of a complex number and its additive inverse is zero. The additive inverse of the complex number is 2+ 8i

A complex number is said to be additive if  the sum of a complex number and its additive inverse is zero.

For instance the the additive inverse of the complex number a+bi is -a-bi.

Given the comlex number -2 + 8i, the additive inverse is expressed as:

Additive inverse = -(-2 - 8i)

Additive inverse = 2 + 8i

Hence the additive inverse of the complex number is 2+ 8i

Answer:

The width should be more than 5 m. So it can be  6,7 ...

Step-by-step explanation:

The length of a flower garden is = 9 m

The width of a flower garden is   = w

The area of a flower garden > 45 sq. m

The area of a flower garden  = l * b

l * b > 45

9 * b > 45

the width should be more than 5 m. So it can be  6,7 ...

It is asking for the absolute value of 18. The absolute value is the units away from 0 the number is, so the answer is 18.

Answer: the answer is 1^19 (one to the power of 19)

Step-by-step explanation:

 l^18 multiplied by l^1 = l^(18 + 1) = l^19

(1 to the power of 18 multiplied by 1 to the power of 1 equals 1 to the power of (18 + 1) equals 1 to the power of 19)

Answer:

y=2x+1.

Step-by-step explanation:

You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.

Answer:

40mph

Step-by-step explanation:

Using D = rt, the current variables we have are

D = 20 miles

t = 30 minutes

Since the goal is rate, we alter the equation to r = D/t.

In addition, we have to convert minutes into hours so we can

r = (20 / 30)*2/2

r = (40/60)

60 minutes is converted into an hour so the rate r is 40 miles per hour.

r = 40/1

Answer:

Step-by-step explanation:

The given equation is true for x=-5/3.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 7x-2(x+1)+18 = 8x-11.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The solution for the equation 7x-2(x+1)+18 = 8x-11 is as follows

7x-2x-2+18 = 8x-11

⇒ 5x-16=8x-11

⇒ 8x-5x=-16+11

⇒ 3x=-5

⇒ x=-5/3

Verification:

Substitute x=-5/3 in the given equation and verify

That is, 5(-5/3)-16=8(-5/3)-11

⇒ -25/3 -16=-40/3 -11

⇒ (-25-48)/3 = (-40-33)/3

⇒ -73/3 =-73/3

LHS = RHS

Therefore, the given equation is true for x=-5/3.

Answer: Lunch:$16 Coffee: $4 Julie had $12 left.

Step-by-step explanation:

Answer:

1. Lunch ($16)

2. Coffee ($4)

3. how much money did she have left?

she had ($12) left

Step-by-step explanation:

1. To get the amount of money she used on lunch you have to look at the word problem it says "she spent 1/2 of her money on lunch" her total is $32 dollars and 1/2 is .5 as a decimal and 50% as a percentage so 50% of 32 is (16) so she spent $16 dollars on lunch alone.

2. To find how much money she used on Coffee you need to read the context of the problem its asking for "how much did she use of the money that is left from her lunch"   so she has $16 dollars she used from lunch so now it wants you to find 1/4 of $16 dollars or 25% of 16 and 25% of 16 is (4)

so she spent 4 dollars of what was left so the answer is 4.

3. To find how much is left add up 16 and 4 and you get 20 then subtract it by the original number which is 32 so it should look like this 32 - 20 = 12

so the money she has left is $12 dollars.
