Answer:
Janet has coins worth 252.5, 101, and 50.5.
Step-by-step explanation:
Let us call the three coins , and .
The first coin is 5 times another coin<em> (let's say </em>); therefore,
,
and the third coin is 2 times the value of another coin<em> (it's coin </em><em>):</em>
<em /><em>.</em>
The total worth of all coins is 404; therefore,
or
with the value of in hand, we find and :
and for
Thus, Janet has 3 coins worth 252.5, 101, and 50.5.
Answer:
3.) 63=3x+7y
4.) Y-intercept is 9
Step-by-step explanation:
(For 3) For every time a person gets a touchdown, x represents that
for every time a person person scored a successful extra-point attempt, y represents that.
And they team scores 63, so....
the equation would look like this
63=3x+7y
(For 4) You find the y-intercept by turning the standard form equatio into the slop intercept form
(Helper's note, multiplying by its reciprocal is the same as dividing it by a whole number, in the case dividing the number by 7 is the save as multiplying the number by )
Then plugging x=0 and solve for y, which in this case, y=9
(For the graphing) Turn 63=3x+7y into a slope intercept form, which is and graph from there
To get the Greates Common Factor (GCF) of 84 and 210 we need to factor each value first and then we choose all the copies of factors and multiply them:
<span><span>84: 223 7</span><span>210: 2 357</span><span>GCF: 2 3 7</span></span>
<span>The Greates Common Factor (GCF) is: 2 x 3 x 7 = 42</span>

The angle x is half the sum of the intercepted arcs, PQ and NO.
... (1/2)(65° + 45°) = 55° = x° = m∠PMQ
