Answer:
multiply the magnitudes of the numbers; affix a negative sign.
Step-by-step explanation:
The product of a positive number and a negative number is the negative of the product of their numerical values.
For example, ...
(2)(-3) = -(2×3) = -6
(-2)(3) = -(2×3) = -6
Answer:
Whenever you multiply two numbers with different signs, the answer is always NEGATIVE.
A rate is a ratio that compares
Rate is ratio that compares two quantities of different units.
What is rate?A rate is a special ratio in which the two terms are in different units. Rate can also be defined as the ratio between two quantities of different units
For example, velocity is an example of rate, because it defined by the ratio of distance covered and time.
The unit of distance is metres and the unit of time is second. Therefore ;
velocity = distance /time. Therefore velocity is a rate.
Another example is ; Ade eat 5 mangoes for 20 days. The rate at which Ade eat is
1 day = 5/20
= 1/4 mangoes. This means Ade eats 1/4 mangoes per day.

What is the answer to: 5t+16=6-5t
Answer:
[tex]\boxed {t = -1}[/tex]
Step-by-step explanation:
Solve for the value of [tex]t[/tex]:
[tex]5t + 16 = 6 - 5t[/tex]
-Take [tex]5t[/tex] and add to [tex]5t[/tex]:
[tex]5t + 16 + 5t = 6 - 5t + 5t[/tex]
[tex]10t + 16 = 6[/tex]
-Subtract [tex]16[/tex] to both sides:
[tex]10t + 16 - 16 = 6 - 16[/tex]
[tex]10t = -10[/tex]
-Divide both sides by [tex]10[/tex]:
[tex]\frac{10t}{10} = \frac{-10}{10}[/tex]
[tex]\boxed {t = -1}[/tex]
So, the value of [tex]t[/tex] is [tex]-1[/tex].

Richard uses the polynomial 40x^2+350 to decide how much to charge for his paintings.In each polynomial x is the height of the painting in feet. To the nearest tenth for what height will both Claire and Richard charge the same amount for a painting?
Answer:
3.2 ft

Lorenzo has 4 packages of granola bars. Each package has 10 bars. He eats one bar from each package.
Answer:
4x10-4=36
Step-by-step explanation:
Lorenzo ate 1 bar from each. so 36 is left.
Answer:
4 × 10 - 4 = 36 granola bars
Step-by-step explanation:
4 packages with 10 bars each means 40 bars (4 packages × 10 bars each = 40 bars total)
one bar from each package
there are 4 packages so if he eats only one from each then he eats 4 bars total
40 bars total - 4 bars he ate = 36 bars left over

Answer:
This equation has 4 solutions, its real solutions are x = -1 and 3
Step-by-step explanation:
Correct for Plato Users
The equation has 4 solutions and its real solutions are 3, -1.
The given polynomial equation is 6(x - 3)(x² + 4)(x + 1) = 0.
What does a real solution mean in math?A real solution in algebra is simply a solution to an equation that is a real number.
Now, 6(x - 3)(x² + 4)(x + 1) = 0
⇒(x - 3)(x² + 4)(x + 1) = 0
⇒(x - 3)=0, (x² + 4)=0 and (x + 1) = 0
⇒x=3, -1 and ±√-4.
Therefore, the equation has 4 solutions and its real solutions are 3, -1.

Answer:
6 = b or b = 6
Step-by-step explanation:
3.7b + 7 = 8.1b - 19.4
Subtract 3.7b from 8.1b. Add 19.4 to 7.
26.4 = 4.4b
(26.4)/(4.4) = b

Every musician in the band plays either the flute or the drum (but not both). The ratio of flutists to drummers is 7 : 1. If 2 drummers join the group and 6 flutists quit, the ratio of flutists to drummers would be 3 : 1. How many musicians were in the original ensemble? 4. A sloth is swimming in the Charles River at 20 feet per minute. How fast is the sloth swimming in smoots per hour? One smoot is equal to 5 feet, 7 inches. Write your final answer as a simplified fraction.
Answer:
Number of drummers in original ensemble [tex]=3[/tex]
Number of flutists in original ensemble [tex]=21[/tex]
Step-by-step explanation:
The ratio of flutists to drummers is [tex]7:1[/tex]
Let number of flutists and drummers be [tex]7x[/tex] and [tex]x[/tex].
As 2 drummers join the group and 6 flutists quit,
Number of drummers = [tex]x+2[/tex]
Number of flutists = [tex]7x-6[/tex]
New ratio of flutists to drummers = [tex]3:1[/tex]
So,
[tex]\frac{7x-6}{x+2}=\frac{3}{1}\\ 7x-6=3(x+2)\\7x-6=3x+6\\7x-3x=6+6\\4x=12\\x=3[/tex]
So,
Number of drummers in original ensemble [tex]=x=3[/tex]
Number of flutists in original ensemble [tex]=7x=7(3)=21[/tex]

Write an equation for a line that is parallel to 3y = 2x - 3 and passes through the point (-3, 4).
Answer:
Step-by-step explanation:
You keep the same slope since it's supposed to be parallel. But first you need to write it in slope intercept form. So the y can't have a number in front of it, so you must divided everything after the equal sign by the 3. So the equation becomes y=2/3x−1. Now you plug in the points to find a parallel equation using point slope form y−(4)=(23)(x−(−3)). Then you solve that and you get y=2/3x+6.
