For this case we have the following equation:

(3 * 7) + 5 = 26

To do this, we propose the following situation:

Andrea raised $ 3 every day, for a week (including Saturday and Sunday), after helping her aunt decorating the garden.

In addition, Andrea had saved $5 from her father.

How much money does Andrea have in total?

So, if I raise $3 every day of the week we have:

3 * 7

To that amount we add $ 5:

(3 * 7) + 5 =\\26

ANswer:

(3 * 7) + 5 = 26

Graph x+3y<(or equal to)6, indicating the solution set with cross hatching or shading. Explain how you determine where to dra
Sergeu [11.5K]

Step 1

Given;

x+3y\leq6

Required; To graph the inequality

Step 2

Graph the function

\begin{gathered} We\text{ find the y-intercept by setting x=0} \\ 0+3y\leq6 \\ y\leq2 \\ First\text{ point\lparen0,2\rparen} \end{gathered}\begin{gathered} We\text{ find the x-intercept by setting y=0} \\ x+3(0)\leq6 \\ x\leq6 \\ Secon\text{d point;\lparen6,0\rparen} \end{gathered}

So by finding the x-intercept and y-intercept, we can determine where to draw the line. Since the inequality is greater than or equal to the line will be continuous and not broken. Also, we will know the area we will shade by;

\begin{gathered} Resolving\text{ the inequality and make y the subject of the formular} \\ x+3y\leq6 \\ 3y\leq6-x \\ y\leq2-\frac{x}{3} \end{gathered}

Since if we set x=0, we get y < or equal to 2, then we know that the shaded area will be where y is equal to and below. There we will shade below the point (0,2) to represent the solution set.

WILL GIVE BRAINLIEST TO PERSON WHO ANSWERS CORRECTLY!!!!!
MAVERICK [17]
7 < x. Here, you can solve the inequality by multiplying 2 by each quantity in the parentheses to get -18 < 24 - 6x. You can subtract -24 from both sides to get -42 < -6x. Then, you can divide each side by -6 and flip the inequality, and this leaves you with x > 7. You would check this answer by choosing a number greater than but close to 7, using the original equation.

Find value of y and x
Vika [28.1K]
Since the triangle is isosceles the measure of angle B is also 47.
since you have dropped a perpendicular bisector the measure of angle x is 90. and since the angles must add to 180 you get 47+47+a=180 and a= 86. since y is half this we have y is 43

if you like my answer please rate as brainliest! thx

a fair die is tossed four times. Find the probability of obtaining each of the following. 5 on all four tosses
Anastaziya [24]

Answer:

\dfrac{1}{1296}

Step-by-step explanation:

When a fair die is tossed once, there are 6 possible outcomes: 1, 2, 3, 4, 5, 6.

The probability of rolling 5 is \dfrac{1}{6}.

When a fair die is tossed four times, the probability of rolling 5 all four times is

\dfrac{1}{6}\cdot \dfrac{1}{6}\cdot \dfrac{1}{6}\cdot \dfrac{1}{6}=\dfrac{1}{6^4}= \dfrac{1}{1296}
