X= 4! If you fill it in it’s 5(4) + 3= 23. Which goes to 20 + 3= 23

Listen i know its dumb but- solve for w 10 + w = -9

Darya [45]

Answer:

w = -19

Explanation:

To solve this equation, subtract ten from both sides. This will isolate the variable (w) and allow us to find its value.

$10 + w = -9\\(10 - 10) + w = (-9 - 10)\\w = (-9 - 10)\\w = -19$

If you would like to double check that the variable (w) does in fact equal negative nineteen, substitute the value of the variable in the equation and solve.

$10 + w = -9\\10 + -19 = -9\\-19 = -19 [true]$

Therefore, the value of w in the given equation is -19.

The difference of two numbers is 74. Twice the first and thrice the Second sum up to 138. Find the two possible numbers . anyone

antiseptic1488 [7]

Answer:

72 and -2

Step-by-step explanation:

x - y = 74

2x + 3y = 138

x - y = 74

y = x - 74

2x + 3(x - 74) = 138

2x + 3x - 222 = 138

5x = 360

x = 72

x - y = 74

72 - y = 74

-y = 2

y = -2

Cal is measuring temperature changes in four substances over different time periods as part of a school project. Which data show

djyliett [7]

Answer:

C) The third table. K= 5

$C)\frac{10}{2}=\frac{15}{3}=\frac{25}{5}=\frac{40}{8}=k= 5$

Step-by-step explanation:

1) Below there are the missing data:

A proportional relationship through a constant k. It is obtained when we divide:

$k=\frac{y}{x}$

2)In this case, when we divide the temperature (T) by the time (h).

$k=\frac{T}{h}$

3)So, examining the table below we are searching for a ratio k common to all measures (temperatures over hour).

$A) \frac{12}{3}\neq\frac{25}{5}\neq\frac{36}{6}\neq\frac{81}{9}\\B) \frac{22.5}{3}\neq\frac{30}{4}\neq\frac{52.5}{7}\neq\frac{67.5}{8}\\C)\frac{10}{2}=\frac{15}{3}=\frac{25}{5}=\frac{40}{8}=k= 5\\D)\frac{8.5}{2}\neq\frac{22.5}{5}\neq\frac{28.5}{7}\neq\frac{36}{8}$
