3. We want to solve using properties;

\begin{gathered} 5\times23\times2 \\ =5\times2\times23 \\ =5\times2\times(20+3) \\ =10\times(20+3) \\ =(10\times20)+(10\times3) \\ =200+30 \\ =230 \end{gathered}

It simply involve trying to reduce numbers to their simpliest form to make multiplication and addition easy without using calculator.

like; 21=20+1, 39=40-1 etc.

4. Given;

\begin{gathered} 8\times51 \\ =8\times(50+1) \\ =8\times50+8\times1 \\ =400+8 \\ =408 \end{gathered}

Write the slope- intercept form of the equation of the line passing through the point (3,5) and parallel to the line y=3x+6.
seropon [69]

Answer: The gradient of the line passing through is 3, thus the equation of the line becomes y=3x-4.

Step-by-step explanation: The parallel lines gradients that have similar gradients, so now we have the gradient of 3 because its similar to the other gradient. To get the equation of the line we use this equation: y=mx+c, we have to substitute the x and y to get the constant c.

5=3(3)+c

c= -4

y=3x+c

Can someone help me with this problem
Romashka [77]

Step-by-step explanation:

Find the slope of JK by the formula :y2-y1/(x2-x1) whose value is 4/5

similarly, calculate the slope of GH it's value is also 4/5

Find slope of GK now by same formula y2-y1/( x2-x1 ).the value will be -5/3

Similarly calculate slope of HJ and you will get its value to be -5/3

since parallel lines have equal slopes JK and GH are parallel and GK and HJ are parallel. Since opposite sides are parallel GHJk is parallelogram

Lila decided to make more baked goods for the bake sale. She used 1/8 lb less flour to make bread than to make cookies. She used
lord [1]

Answer:

Ok so we are trying to find out how much flour she used to make brownies so we already know that she used 1/2 flour to make bread and She uses 1/8 flour less flour to make bread than to make cookies so if we add 1/2 and 1/8 we will get the amount of flour she used to make the cookies so 1/2 + 1/8 = 5/8 so now that we have the amount of flour she used to make the cookies  we know that that is 1/4 more flour than brownies so if we subtract 5/8 by 1/4 we will get are answer to how much flour she uses to make brownies so 5/8 - 1/4 = 3/8 and that's your answer do you understand?
