What number is 4 times as many as 25

2 answers:

6 0

This is a standard relationship/systems of equations question. Here is how you attack it. Firstly, set up equations to represent the relationships. Ed = 4*Kim That shows that Ed has four times as many pins as Kim. Next, we see that the two have 25 together. So: Ed + Kim = 25 Now we have our two equations. In order to solve, we need to get one of the equations down to one variable. We can achieve this via substitution. The first equation tells us that we can substitute 4*Kim for Ed (in the second equation). So, let's do just that: 4*Kim + Kim = 255*Kim = 25Kim = 5 Using the first equation again, we can solve for Ed: Ed = 4*KimEd = 4*(5)<span>Ed = 20</span>

Just multiply 4 by 25. You get 100.

What is the value of the expression below when z = 6

Oduvanchick [21]

Answer:

Step-by-step explanation:

$2z^2+2z-3$

Using PEMDAS/BODMAS, we will have to do the exponent first, which is $z^{2}$ .

Substitute the variable z with 6, since z = 6.

$2(6^{2} )+2(6)-3$

$6^{2} =36$ .

Thus, we will get

$2(36)+2(6)-3$

Solve the multiplication next.

$72+12-3$

Finally, add/subtract the numbers:

$84-3$

$81$

sladkih [1.3K]

Answer:

−15

Step-by-step explanation:

9−6+5−3+6−2+8(4−7)

=3+5−3+6−2+8(4−7)

=3+2+6−2+8(4−7)

=3+2+4+8(4−7)

=3+6+8(4−7)

=9+8(4−7)

=9+(8)(−3)

=9+−24

=−15

If 24 ÷ b = 12, which number is being subtracted 12 times in order for the answer to be zero?

mariarad [96]

Answer:

Step-by-step explanation:

Notice the question of which number is being subtracted 12 times in order for the answer to be zero is the same as finding b.

Notice 24 is being divided by b to get 12 as result.

The question is then: by what number we divide 24 to get 12?

It is 2 since:

$24\div2=12$
