Http://www.americanrhetoric.com/speeches/mlkihaveadream.htm <span>"I Have a Dream" is a public speech delivered by American civil rights activist Martin Luther King, Jr. during the March on Washington for Jobs and Freedom on August 28, 1963, in which he calls for an end to racism in the United States and called for civil and economic rights. Delivered to over 250,000 civil rights supporters from the steps of the Lincoln Memorial in Washington, D.C., the speech was a defining moment of the American Civil Rights Movement.</span>
Answer:
<em>x</em> = 3
<em>y</em> = -7
Step-by-step explanation:
<em>y</em> = -4<em>x </em>+ 5
<em>y </em>= 3<em>x </em>- 16
<u>Substitute </u><u><em>y</em></u><u> in the first equation with 3</u><u><em>x</em></u><u> - 16</u>
3<em>x</em> - 16 = -4<em>x </em>+ 5
+4<em>x </em>+4<em>x</em>
7<em>x</em> - 16 = 5
+16 +16
7<em>x</em> = 21
÷7 ÷7
<em>x</em> = 3
<u>Then, put </u><u><em>x</em></u><u> = 3 in </u><u><em>y</em></u><u> = -4</u><u><em>x</em></u><u> + 5</u>
<em>y</em> = -4(3) + 5
<em>y</em> = -12 + 5
<em>y</em> = -7
Answer:
pieces
Step-by-step explanation:
Suppose you have a 7 feet long wood.
You need to find how many -foot pieces can be cut from this wood.
To find this number of pieces, you have to divide the whole length of the wood by the length of one piece:
Answer:
The measures of the angles of the triangle are 96° , 36° and 48°.
Step-by-step explanation:
The ratios of the angles of a triangle = 8 : 3 : 4
Let x be the common factor in the ratio.
⇒The angles of the triangle is 8 x, 3 x and 4 x.
Now, By ANGLE SUM PROPERTY of a triangle:
Sum of all interior angles of a any given triangle is always 180°.
So, here 8x + 3x+ 4x = 180°
or, 15x = 180°
or, x = 180° / 15 = 12
⇒ x = 12
So, the <u>first angle</u> of the triangle = 8x = 8 x 12 = 96°
<u>Second angle</u> of the triangle = 3x = 3 x 12 = 36°
<u>Third angle</u> of the triangle = 4x = 4 x 12 = 48°
